Abstract :-The research paper examines the seismic behavior of buildings with soft storeys, which are high-rise structures where the ground floor is open, often for parking. These soft storey create significant changes in the building’s lateral stiffness and strength, impacting the building’s performance during earthquakes. The study focuses on understanding how soft storeys affect seismic parameters such as storey drift, displacement, base shear, and storey overturning moments. The research evaluates buildings with soft storeys at different levels, using the Equivalent Static Method and seismic analysis through ETABS. It finds that shifting the soft storey to higher floors reduces displacement, and different structural systems can help reduce lateral displacement and story drift. The paper aims to assess the effects of soft storeys in various earthquake zones and with different column shapes. Keywords: Soft Storey, ETABS, Storey Drift, Equivalent Static Method, Response Reduction Factor.

Abstract In this paper (G+8) building is modeled like a bare frame, a bare frame with the shear wall, and a bare frame with X bracing by changing the soft storey to different floors. The static analysis effect is determined for all three models with zone IV and zone V using Staad pro-V8i software. The main objective of the research was to assess the impact of a soft storey in various earthquake zones and by varying places of the soft storey from first to the top floor and for frames with different column shapes by seismic analyses in staad pro. The results of variable building models are obtained from the research regarding various parameters such as displacement, storey drift, and base shear. More significantly, comparing different structural systems revealed a reduction in lateral displacement and story drift. The shear wall reduced the Storey Displacement by 98.838% and storey drift by 99.86%. The Steel bracing reduced the Storey Displacement by 97.846 % and storey drift by 92.6%. Finally, it has been found that the Shear wall reduces lateral displacement and storey drift, thus significantly contributing to greater structural stiffness. The analysis results recommended that the shear wall use reinforced concrete frames for the seismic hazard zones and the Steel bracing recommended for the low seismic zones.

Abstract: Structural analysis is the science of determining the effects of different loads on structures. Structural stability and stiffness are a main concern in any high-rise structures. Shear walls are structural members that are mainly responsible for resisting lateral loads predominant on structures. They are mainly responsible to increase the stiffness, reduce story drift and displacement. In order to have a comprehensive understanding about the contribution of shear wall, following research is carried out. This research involves comparing two G+16 structures; one without a shear wall and one with it. The structure has 4 bays of 3m each along X direction and Z direction. In this, we will see how shear wall resists lateral sway and reduces story drift and increases stiffness. As the height increases, the shear wall absorbs more lateral load than the frame. The software to be used for analysis is STAADPro. Keywords: STAADPro, Stiffness, storey displacement, storey drift.

In seismically active places, earthquake restrictions would provide a difficulty to the majority of multistory buildings. The fundamental issue in the design of the multi-story building is lateral stability, which is required to control lateral drift and displacement, withstand lateral pressures, and avoid buckling. Reinforced concrete (RCC) structures usually utilise a damper, bracing, and shear wall system to mitigate the impacts of seismic activity. Both systems have significant structural performance. Despite the fact that both technologies are used for the same purposes, their effects and behaviour in response to seismic load differ. The G+12 storey building, shear wall and bracings will all be considered in this project's analysis. The following criteria will be used to evaluate the building's performance: base shear, storey displacement, and storey drift. This research includes dampers, shear walls, and bracings at various places, and the Etabs 2018 programme will be utilised for the entire analysis.

Open ground storey or soft storey is a typical feature in multistory structures in urban areas. This open storey is provided to accommodate parking, reception lobbies, office, communication hall etc. Many of structure having soft storey suffered major damage and collapsed in recent earthquakes. During an earthquake, because of variation in stiffness in soft story and its adjacent floors the inter story drift can occur and the lateral forces cannot be well distributed along the height of building. Lateral forces concentrate on soft story causes large displacement. In this work, an attempt has been made to observe the behavior of gradual decrease in stiffness of building, by using different types of infill material. This work discusses Optimum Earthquake response of tall buildings by response spectrum method as per IS 1893:2002 (Part- I) in ETAB’S software. Seismic parameters like storey stiffness and storey displacement are checked out.

In Multistoried building design, lateral load ((i.e. wind or earthquake loads) are mainly responsible for drift which very often dictates in selection of structural system for high rid. To bring the maximum drift down to allowable limits, cross sectional of beams and columns have to increase in many case. For buildings having small number of storey, lateral load rarely affect of the building increase, the increase in size of structural members and possible rearrangements of the structure to account for lateral load. The lateral displacement in moment frames is the greatest among the other lateral load resisting systems investigated; the lateral displacement in dual frames is the least while the lateral displacement in shear wall systems is slightly higher than that of the dual system

ETABS stands for three-dimensional analysis of building systems. ETABS is commonly used to analyze skyscrapers, concrete structure low- and high-rise buildings, this project mainly highlights for structural behavior of multi-story buildings with 2 different plan configurations like H shape and S shape modeling of 10-stories RCC framed buildings done on the ETABS software for analysis. Post-analysis of the structure included base shear, storey forces, story displacement, storey drift and then compared. The presence of irregularity in buildings is a matter of concern when it is subjected to devastating earthquakes. A rapid change in vertical or plan configuration in buildings inclines to fail the structure. To prevent failure and diminish the risk potential of irregular buildings, the responses of such buildings to horizontal loads have to be studied in detail. The responses of unstable structures are analyzed using Static linear analysis, the models are analyzed to study their effect as per IS 1893 (Part 1): 2016 codal provisions. The parameters considered in this study are story displacement, storey drift, and lateral displacement. The results of the irregular construction have conversed.

The present study focuses on the use of coupled shear walls with and without dampers for resisting seismic loads. Multistory structures with and without shear walls are analysed. Different parameters, such as the structure's base shear, storey drift, storey displacement, storey stiffness, and storey shear, are evaluated, and a comparative study is performed. It is observed that coupled shear walls with fluid viscous dampers reduce storey drift by 24% and storey displacement by 45% when compared to buildings without shear walls. A coupled shear wall with a damper has a 29% higher stiffness than a coupled shear wall without a damper, thus performing effectively in resisting lateral forces induced by an earthquake.

A soft storey or a weak storey is one in which the lateral stiffness is less than 70 percent of that in the storey above or it can be less than 80 percent of the average lateral stiffness of the three stories above. For the reduction of lateral deflection of a structure, a bracing system is provided. In seismic design of structure and in high rise structure, the provision of bracing system has become more effective. So this paper aims to find out the effect of bracing on soft storey of steel building. In this paper, G+9 steel frames are modeled with different type of bracing pattern and different combination of soft story using software STAAD Pro. Effect of these different bracings on soft storey is studied for different parameter like column displacement, maximum deflection, storey drift, maximum bending moment, maximum axial force and maximum shear force. From the observed result best type of bracing will be selected.

Tall building construction and developments have been rapidly increasing worldwide Development of metro cities in India there is increasing demand in High Rise Building and it is common to use the effect of masonry infill panel on the response of RC frame subjected to seismic action. In this study the effect of seismic load on soft storey building using diagonal bracing with visco elastic damper wall on high rise building is studied, because the effect of diagonal bracing must be considered for the seismic evaluation of moment resistant reinforced concrete frames Linear analysis is performed on high rise structures with various arrangements, and a G + 19 framed building is modelled for analysis. ETABS software performs all analysis. Base shear, storey displacement, and storey drift are calculated and compared for all models in this software, and the results show that the time period decreases with the incorporation of bracing with viscoelastic damper. Soft storey in high-rise buildings has a significant impact on seismic performance. The variation in floor height causes a discontinuity in the rigidity of the structure at the soft storey level. Soft storeys with varying floor heights. In this way , models are analysed . ETABS software has been used for analysis purpose which results in terms of max moment , max storey , max shear force , displacement , max axial force and drift which are critically analysed to quantify the effect of various parameters . The soft storey building with diagonal steel brace dampers is most effective and economical in seismic active areas Soft stories are subjected to larger lateral loads during earthquakes and under lateral loading. This lateral force cannot be distributed evenly along the structure's height. Because of this, the lateral forces are concentrated on the storey with the greatest displacement. The lateral force distribution along a building's height is directly related to the mass and stiffness of each storey. As a result, the dynamic analysis procedure provides more accurate distribution results of earthquake and lateral forces, as well as building height, determining the modal effects and local ductility in efficient demand.

Multi-storey building would be the greater part influenced by quake constrains to seismic prone areas. The major concern in the design of the multi-Storey building is the structure to have enough lateral stability to resist lateral forces buckling to control lateral drift and displacement of the building. The application of the shear wall system in Reinforcement concrete (RC) building has been widely used to minimize seismic consequences. Besides, the building with concentrated steel bracing system is used for the building. Both of the system has significance of the structural performance. Although both systems are used for same reason, their effect shows unequal variation and behaviours against seismic load. In the Project, G+10 storey building, along with shear wall and bracing are being considered for the analysis. The performance of building will be evaluated on the basis of following parameters Story displacement, Storey drift. In this work, the shear wall and bracing are provided at different locations with the overall analysis to be carried out using STAAD PRO Reinforced concrete structures are in greater demands in construction because the construction becomes quite convenient and economical in nature. RCC construction is best suited for low rise building but in High rise building construction are composite is a better option among the RCC and steel Structure.

The development of tall buildings has been rapidly increasing worldwide, introducing new challenges that need to be met through engineering judgment. One effective structural system used to control excessive drift due to lateral loads is the outrigger system. This system minimizes the risk of structural and non-structural damage during small or medium lateral loads caused by wind or earthquakes. Particularly for high-rise buildings in seismically active zones, the outrigger system is a suitable structural choice. This thesis employs ETABS 21.0.0 software to analyze the performance of vertical irregularities in outrigger structures through Response Spectrum Analysis. The objective of this study is to investigate the behavior of outriggers under lateral loads, optimize outrigger location, and evaluate the efficiency of each outrigger when outriggers are used at different story heights. 30-storey three-dimensional models, with and without outrigger and belt truss systems are used subjected to wind and earthquake loads. These models are analyzed and compared to determine the story drift, story displacement, and base shear reduction associated with different outrigger and belt truss system locations. The study includes a comprehensive analysis of story displacement, story drift, and base shear of the structure.

In this paper the incorporated irregularities are as per IS1893 (Part )1:2016 and study response of 12 story building frame 13 models with mass irregular, stiffness irregular and vertical geometric irregularities are analyze in ETABS 2017 by linear dynamic analysis i.e. Response spectrum Analysis. The various structural response parameters such as maximum storey displacement, inter story drift and storey shear are taken to compare the result. Mass irregularity is placed in fourth story, stiffness irregularity is provided in first storey and vertical geometric irregularity is provided in different upper floor. It is concluded that the soft story at bottom highly increases the lateral displacement of that floor, mass irregular at fourth story highly increases the storey shear below that storey and vertical geometric irregularity effect on the relative displacement of building. Combined irregularity highly effect performance of the building therefore chance of collapse also increases as increases in irregularities. All the comparison are represented graphically.

Abstract: The high-rise building in which ground storey consists of open space is known as building with soft floor. Such floor plays an important role in seismic performance of the building. This is due to the abrupt changes in lateral stiffness and strength caused by such storey. In the present era there is increase in population, finding parking for flats in congested areas has become a significant issue. As a result, erecting multistory structures with an open first floor is now a widespread practice. These Buildings that have all upper storeys enclosed by masonry walls but no infill masonry walls in the ground story are referred to as "Soft Storey" or "Open Ground Storey Buildings." Compared to regular buildings, irregular structures the drift is observed to be effectively reduced by larger columns, while the shear force and bending moment on the first floor are increased. During a violent earthquake, the Soft Storey buildings function poorly. Understanding the behavior of is this study's primary goal to the building in a seismically active area and to assess the effects of Storey overturning moments, Storey drift, displacement, and design Base shear. For comparison, G-15 story building with five completely distinct shapes a square, an L-shaped building, a Tshaped building, a plus shape building and a C-shaped building is used. ETABS 2018 version is used to analyze the entire set of models. Dynamic Analysis has been examined in the current work to assess the deformation of all five-shape building with and without soft storey considering at different level. When the soft story is offered at a higher level, displacement is reduced. Several studies on this subject that have been done in the past are reviewed in this paper. Reviewing research papers let us know about the conclusive results, which served as the basis for the objective of our future study.

In today's scenario, one of the greatest challenges for structural engineers is designing and constructing seismic-resistant structures. Seismic activity, or earthquakes, poses a significant threat to civil engineering structures, and ensuring that buildings can withstand the forces generated during an earthquake is crucial for public safety and infrastructure resilience. Irregular configurations, whether in the building's floor plan or its elevation, are widely acknowledged as significant contributors to failure during seismic events. These irregularities can lead to uneven distribution of forces and stresses, compromising the building's ability to withstand the seismic forces and potentially resulting in structural failure. Soft storeys, typically located at ground levels for various functional purposes, pose challenges in seismic regions due to their lack of sufficient lateral load-resisting elements resulting in excessive lateral deformation and collapse during intensive earthquakes. Hence, the present study investigated the seismic response of irregular reinforced concrete structures possessing stiffness irregularity at ground floor with and without shear walls. A ten-storey regular frame is modified by incorporating vertical irregularity in elevation by increasing the height of the ground floor. The complete structural analysis and modeling are carried out by using the software ETABS 2020. The Time History method is applied, and the study is focused on seismic zones V in India. The performance of structures are compared based on criteria such as storey displacement, storey drift, storey shear and overturning moment. The results lead to the conclusion that a building structure exhibiting stiffness irregularity is prone to instability which is indicated by higher displacement and drift values. Structures incorporating shear walls have demonstrated greater stability compared to structures without shear wall as they exhibited higher base shear values and experienced a reduction in lateral displacement by more than 40%. The presence of shear walls also has enhanced the stability and strength of the structure, showing a linear response during critical earthquakes.

The present work has been done by observing the behaviour of outrigger structure using non dimensional parameter α and β under the action of earthquake load. The earthquake load calculation has been done by IS 1893 (Part-1):2016. In the structure, the outriggers and belt truss are placed at two different locations. The location has been decided by the study of many research paper that at top level of the building (i.e., floor no. 40) and other at 0.55H of the building (i.e., floor no. 22). In this study the non-dimension parameter α remain constant and β change their value by varying depth of outrigger beams to compare the analysis result. In this research, a 40-story 3D reinforced concrete structure with plan area of 25.0 m X 25.0 m and height of building is 128 m is considered in modelling. Location of first outrigger at 40th floor and second outrigger at 22th floor (0.55H) of the building is also modelled in CSI ETABS V19.0 software considering the time history analysis of proposed work. The depth of first outrigger beam is taken same as the floor height of the 40th floor and for second outrigger beam the depth of beam varied as one storey, one and half storey and two storey depth of floor. Key parameter discussed in this paper includes the lateral displacement, story drift and Base shear. The conclusion comes from the study is that when the stiffness of outrigger beam with belt truss is increased by increasing the depth from one storey to two storeys then it will increase the overall lateral stiffness of model that control storey drift.

The seismic behavior of multi-story buildings is greatly influenced by their structural configuration. Irregularities in plan or elevation, particularly mass irregularities, are critical factors contributing to structural failure during earthquakes. Proper identification and management of such irregularities are essential to optimize a building's functionality and aesthetics. This study examines the seismic response of a G+14 reinforced concrete (RC) frame structure with and without mass irregularity. The analysis focuses on storey drift, storey displacement, lateral loads, maximum bending moments, and shear forces. A swimming pool placed on the 7th floor introduces a heavy mass, creating mass irregularity as per IS 1893 (Part 1):2016, where a floor’s seismic weight exceeds 150% of the floors above and below. Using STAAD.Pro Connect Edition software, the structures are analysed through dynamic response spectrum analysis. The residential building, with dimensions of 35.45 m × 30.56 m, is subjected to seismic loads according to IS code standards. Results indicate that the inclusion of mass irregularity significantly impacts the seismic response, leading to notable variations in drift, displacement, and internal force distribution. This study highlights the importance of addressing mass irregularities in seismic design to ensure structural safety and performance in earthquake-prone areas. Keywords: Mass irregularity, seismic response, RC frame, STAAD.Pro, storey drift, response spectrum, IS 1893:2016, dynamic analysis.

Bangladesh, a densely populated country in South Asia, is located in the north eastern part of the Indian subcontinent at the head of the Bay of Bengal. Geographical location of Bangladesh makes it ideally suited to earthquake and wind pressure. So, the knowledge of dynamic analysis is essential for civil engineers to design a safe structure for reducing the damages of structure during lateral loading. This paper represents a comparative study of the severity effect of wind forces on a high-rise building applying BNBC 2006.To achieve this goal a plan of 10 storied high-rise building has been considered. The study performed with 12 variation of wind speed from 150 km/hr to 260 km/hr. The analysis has been done by using computer software ETABS. After the analysis the maximum displacement was found 12.9 inch at 260 km/hr wind speed with top storey drift was found 0.0191 at 110ft whereas the lowest displacement and drift value was found 8.875 inch and 0.0153 at wind speed of 150 km/hr considering similar height of 110ft. This paper overviews the entire effect of different wind speed on high rise structure to predict the lateral movements such as displacement and inter-storey drift as well as serviceability of a RC building.

Base isolation is an effective way to protect large structures from earthquake damage. It is a costly approach, as the entire structure must be supported on elastomeric or sliding bearings. Viscous dampers distributed throughout an otherwise conventional structure can achieve the same result at a significantly lower cost. Dampers are used to resist lateral forces coming on the structure. Dampers are the energy dissipating devices which also resist displacement of Reinforced Concrete (RC) buildings during an earthquake. These dampers help the structure to reduce buckling of columns thereby increasing the stiffness of the structure. During earthquakes, multi-storeyed buildings get damaged and as a result, large deformation occurs. Dampers reduce vibration and deformation of structural elements during an earthquake. Retrofitting buildings with fluid viscous dampers (FVDs) can improve Interstorey drifts and floor accelerations. In the present study, an RC framed building is modelled and analysed under Southern Sumatra and Chile earthquakes to evaluate the performance of the structure and its elements with and without energy dissipators. For the study, a model (G+19) with and without energy dissipators is modelled in ETABS. The seismic force is applied based on the time history data of the models pertaining to Southern Sumatra and Chile Earthquake. Response Spectrum analysis has been carried out to find the lateral displacements, storey shear and Base shear for the model with and without dampers. The lateral displacement, storey drift, storey shear and Base shear are found to less for the model with Linear FVDs when compared to the model with Non-Linear FVDs and without FVDs.

Due to the geological formation of Bangladesh, it is showing the threat of earthquakes. As the number of high-rise buildings is increasing daily, there is an urgent need to design structures considering seismic loading. During earthquakes, structures are subjected to lateral displacement. Most reinforced concrete structures are designed to resist gravity loads, but they neglect the effect of lateral forces arising due to earthquakes. Shear walls are added to the building's interior as well as exterior to provide more strength and stiffness to the building. The studies have been carried out using CSI ETABS (v 16.2.1) software, and the model was developed using Finite Element Method (FEM), the model analysis was done by using Equivalent Static Analysis (ESA). The building under analysis consists of 15 floors. The building is located in Bangladesh's seismic zone – III (Bogura). After the study, various parameters like maximum lateral displacement, storey drift, storey shear, and storey stiffness were compared to find the suitable position of the shear wall.

Full textAbstract:
The force distribution proposed by codes, which in many cases is framed in the equivalent static force procedure, likely leads to design structures with non-uniform drift distribution in terms of inter-storey drift and ductility demands. This can lead to an unbalanced drift demand at certain storeys. This phenomenon may also amass cyclic damage to the dissipative elements at this very storey, therefore increasing the probability of premature failure for low-cycle fatigue. This work proposes a new force design distribution that accounts for higher mode effects and limits the displacement concentration at any storey thus improving the dissipative capacity of the whole structures. The main advantage of the proposed method stands in its formulation, which allows to spare any previous set up with structural analyses. The proposed force distribution has been applied to multi-degree-of-freedom systems to check its effectiveness, and the results have been compared with other proposals. In addition, in order to obtain a further validation of the proposed force distribution, the results obtained by using a genetic algorithm have been evaluated and compared. Additionally, the results provided in this work validate the proposed procedure to develop a more efficient lateral load pattern.

This study is focused on the efficient use of the lateral load-resisting system for high-rise concrete buildings subjected to earthquake load. 32-storey three-dimensional models of OMRF, SMRF, core, core with outrigger (OT), core with outrigger and cap truss, and core with belt truss (BT) and core with belt truss and their cap truss systems are analyzed and compared to find the lateral displacement, storey drift and time-period reduction. The modelling and analysis were performed using finite element software ETABS 2016. The analysis has been carried out to study the effect and performance of the outrigger system and belt truss system in the building. These systems are provided at different levels along the height of the building. The coverage of the outrigger and belt trusses are equal to the height of the typical story and maintained the same in all the models. For finding the optimum position of the outrigger and belt truss system and also with their cap truss, the result is illustrated in terms of the reduction of top-storey lateral deflection, the maximum reduction in storey drift and the maximum reduction in the time period of the building. All the parameters are obtained for the structure without an outrigger system and they are compared with the values obtained by introducing an outrigger and belt truss. A total of 51 models are studied for finding the optimum location and behaviour of the systems when introduced on the building. A comparison is made to find the best system among all the systems, which are introduced in the model. Among the entire systems, an outrigger with a belt truss is found to be the best system in terms of reducing deflection, drift, time and base shear. The optimum position is found to be at 0.375 times the height of the total structure when the user system is outrigger and its belt system in terms of reduction in deflection and time, whereas the optimum position is at mid-height when the selection criterion is lateral drift.

Outrigger structural systems are quite effective using the lateral loads on tall buildings, one of the main benefits of utilization outrigger is that it can reduce deformation and the danger of inter-story drift caused by lateral loads acting on the building. In this case, wind loads will be viewed as a lateral load because the wind load acting on tall buildings can also cause deformation of the building. The implementation of the outrigger system is viewed from different positions to see the deformation that occurs and the placement of the maximum location. The results of the analysis of wind loads reviewed on these buildings have proven that the use of outriggers in buildings can reduce displacement by 19.58%, and inter-storey drifts by 13.24%, which is applied in a position of ½ of the building height. The optimum location of the outrigger installation can also be determined by calculating the analysis of the maximum deflection that occurs on the 40th floor.

In this case neither the structural displacements nor the ground displacements are independent from each other. The phrase ‘soil-structure interaction’ may be defined as influence of the behaviour of soil immediately beneath and around the foundation on the response of soil-structure subjected to either static or dynamic loads. A buckling-restrained brace (BRB) is a structural brace in a building, designed to allow the building to withstand cyclical lateral loadings, typically earthquake-induced loading. It consists of a slender steel core, a concrete casing designed to continuously support the core and prevent buckling under axial compression, and an interface region that prevents undesired interactions between the two. It consists of four models of clay, sand and silt, each one has models as without bracing, with X-bracing, with inverted V-bracing and Y-bracing. It is concluded that X-bracing has less displacement, storey drift and high base shear compared to others. Also, X-bracing with SSI has less displacement, storey drift and high base shear compared to without SSI.

High-rise structures are becoming more common around the world, posing new challenges that necessitate ongoing technological foresight. When a structure’s height rises, it’s anticipated to have a lateral load-resisting system other than shear walls in place to negate the effect of lateral loads. However, advances in structural design and engineering have enabled building systems to withstand lateral forces such as wind and seismic stresses. There are numerous structural solutions tailored to resist lateral forces in the structure without adding to the plan area of the building to stabilize it against lateral load. The Outrigger-belt truss system is a common structural solution for successfully managing excessive drift caused by the lateral load. Hence, in this project, an attempt is made to investigate the characteristics of an Outrigger-Belt truss system. The seismic analysis is limited to the linear static method. A comparative analysis is done using STAAD Pro V8i SS6. Finally, the storey drift and maximum displacements obtained are calculated and the results are compared with the moment-resisting frame and the values are tabulated.

Multi-storey buildings tend to get damaged mainly during earthquake. Seismic analysis is a tool for the estimation of structural response in the process of designing earthquake resistant structures and/or retrofitting vulnerable existing structures. The principle purpose of this work is to analyze and design a building with a shear wall and also to find the appropriate position of shear wall that result in maximum resistance towards lateral forces and minimum displacement of the structure. In this study, a G+7 multi-storey building of 15 m ×20 m in plan area has been chosen and modelled using ETABS. The developed model was validated by solving manually and the results were validated in ETABS. Thereafter, 4 different new plans were modelled in ETABS located in the same earthquake zone area. These plans have shear wall concepts are implemented on the building at four different locations. Seismic, vibration and response spectrum analysis were performed on these structures. Salient parameters such as storey stiffness, storey displacement and storey drift were computed using the ETABS model. These were compared with that of the frame having no shear walls. By comparing the results obtained at different shear wall locations, the best plan with the shear wall having minimum lateral storey displacement and maximum stiffness is suggested for this location.

When a structure is subjected to earthquake forces, vibrations are setup in the structure leading to severe damages to the structure and results in loss of property and life. Now a days, keen attention is given to research and development of vibration control devices to mitigate the seismic effects. The present duty of civil engineer is to discover earthquake resisting design approach to reduce structural damages. The basic technology used to protect the structure from damaging earthquake effects is “base isolation”. The base isolation system decouples the super-structure from the substructure by means of flexible devices through which seismic energy is dissipated. In the present context G+15 storey structure situated in zone V is modeled and analyzed using ETABS-2017 software by providing different base isolation systems namely a) RC structure having fixed base b) RC structure with Fluid Viscous Damper (FVD) and Lead Rubber Bearing (LRB). Response of the structure is studied in terms of story displacement, story drift, base shear, natural time period and design lateral forces. It is found that the provision of Fluid Viscous Damper (FVD) and Lead Rubber Bearing (LRB) in a same structure shows better performance in story displacement, base shear, story drift, natural time period and design lateral forces as compared to fixed base model.

All over the world, the buildings are built in the form of stacks of cubes, generally made of prismatic beam and column. These cubical structures are not having structural integrity. The basic problem with these type of cubes is that these are as strong as there joints are weak, no matter how strong it is held with the ground or how strong is beam or column, it will fail as its joint get cracked. The building may be built stronger against the lateral loading if some braces are provided at the junction. In other words, the haunch beam can resist lateral forces in a better manner. In this paper, a comparative study is done in between two multi-storey building on basis of seismic parameters like time period, base shear, storey drift, maximum storey displacement and maximum storey stiffness.

In many earthquake-prone countries, structures may be suffers to various seismic loads in any stage of structures life. For this situation it is expected that the structures designed will show ductile behaviour under the various loads like vertical loads and lateral loads and also shows a stable behaviour without any major damage. Most of Indian lands behave insecure owing to the vibrations which are caused by the seismic effects. Also, it’s not possible to stop earthquake or vibrations on the structures but it may be controlled by some effective seismic techniques. Pushover analysis is a simply nonlinear analysis to estimate the static and dynamic demand imposed on any structures under earthquake excitation. In now days for design purpose, irregularity in structures is under highly demand. In this paper regular and irregular building structures are taken to study the behaviour during under seismic zone. Here various type highrise buildings are analyzed; behaviour of high rise building during earthquake depends on their structural design. In this study a G+8 rugular structure and multi-storeyed irregular structures are analyzed by nonlinear static pushover analysis. Zone factor for analysis is taken as zone III & zone V. This concerned work all building are designed as per IS 456:2000 and IS1893:2002. The aim of this work is to compare the result of symmetrical and unsymmetrical structure behaviour after applying pushover analysis in behalf of storey drift, storey displacement, base shear and storey shear.

This paper delves into the structural response of irregular buildings, specifically focusing on the influence of geometry and shear wall configurations. Irregular buildings, with their intricate geometries and diverse structural elements, present unique design challenges, necessitating a thorough performance evaluation. Our study conducts a comparative analysis to gauge the impact of various geometric layouts and shear wall arrangements on structural behavior under seismic loading. A nine-story irregular building in Yogyakarta, Indonesia, is a compelling case study. We develop three models (M1, M2, and M3), each incorporating variations in geometry and shear wall configurations (T-shaped, L-shaped, and I-shaped). These models are rigorously analyzed using ETABS software to evaluate key structural responses, including lateral displacement, inter-story drift, and base shear forces. The results reveal that M3 exhibits the lowest base shear, at 24,961.46 kN, 7.582% lower than the existing model (M1). The lowest lateral displacements and inter-story drifts are observed in the x-direction for M2 (26.308 mm displacement, 10.061 mm drift) and in the y-direction for M3 (26.115 mm displacement, 9.339 mm drift). Additionally, the lowest drift ratio occurs on the first floor of M3, measuring 0.110% in the x-direction and 0.115% in the y-direction. These findings underscore the substantial impact of geometric variations and shear wall configurations on the structural response, providing valuable insights into optimizing irregular building designs to enhance seismic performance.

As a consequence of building collapses and other structural damage, the number of lives lost due to earthquakes has risen dramatically over the last several decades across the globe. Such destruction during earthquakes is undeniable proof of the dangers posed by such events to buildings and other facilities, including homes, hospitals, and schools. It was crucial to conduct this research to ensure the efficacy of technology like base isolation and dampers in preventing damage to buildings during tremors. The goal is to ensure the structure doesn't collapse when subjected to lateral pressures. The readings are recorded, compared, and analyzed using response spectra. Recent years have seen extensive focus on enhancing the wind and seismic responses of buildings and bridges via the study and development of structural control systems including passive control system, active control system, and semi active control system. There is no need for electricity to oper-ate a passive control system. Active control systems rely on internal sensors and a constant supply of external electric-ity. Both methods are suitable for usage against earthquakes and high wind speeds. There is no way to completely prevent natural catastrophes from happening. Applying a base isolator and different dampers such a friction pendulum, fluid viscous, or visco elastic significantly reduced the displacement and drift values by 20-30% and 10-20%, respectively. Such measures prevent damage to the building and save lives during earthquakes and other events with high lateral stresses.

A Structural Engineer's principal responsibility is structural design. The design of essential building elements and components is the fundamental principle of structural engineering. The multistory structures are made to save money by expanding the building's floor size without expanding the surrounding land area. Low absorption value, lightweight, flexible, and higher buildings are the result of recent construction trends. During the vibrations the possibility of failure and problems with serviceability will be raised . Tuned mass dampers, or TMDs, have popular device for reducing these lateral vibrations during the earthquake and wind load . The present research uses a Response Spectrum Analysis of a realistic building model with TMD and without TMDs to assess the efficacy of TMDs in vibration management. Important Parameters such base shear, storey drift, maximum displacement, etc were examined. The results show that When actual earthquakes occur in buildings with TMD, there is a noticeable decrease in displacement and Storey Drift,etc values. Buildings that use TMD is better able to withstand the effects of earthquakes.

Abstract This research investigates the impact of thermal loads on reinforced concrete (RC) buildings in Saudi Arabia and how they behave on sloped terrain. The study analyzed the effects of different types of support systems (hinged and fixed supports) and strengthening systems (with and without bracings) using the software ETABS-V20. Ground + 9 typical floors frame RC models on sloped terrain subjected to seismic loads were used for the investigation. The dynamic analysis of the ETABS models was performed to evaluate the lateral displacement, storey drift, column shear forces, and base shear forces of the buildings. The study found that using a bracing system and fixed supports under seismic loads increases the model’s displacement and storey drift compared to models with hinged supports and no bracing system. The maximum shear forces values were also higher for models with bracing systems and fixed supports, while the minimum values were for models without bracing systems and with hinged supports.

Abstract: Due to increasing population with every passing year and the land available for use of habitation is the same as it was a decade ago. So, the only solution to the problem is vertical growth. Now this need for the increase in the vertical height of the buildings has made the buildings tall and slender. The Parameters discussed in this study include Storey Displacement, Storey Drift, Base shear, Storey shear and Time period for static and dynamic behaviour of different lateral load resisting configurations. Based on this parametric study, logical and meaningful conclusion is made for future study considering the safety and economy of the buildings.

Abstract: Infill walls are inevitable components of any structure to create dispassion between interior space and external condition. In general, there are some prevalent openings inside the infill walls because of practical needs, architectural observations or aesthetic inspections. In current design practice, strength and inflexibility contribution of infill walls aren't thought of. However, the presence of infill walls may impact the seismic reaction of structures exposed to earthquake loads and cause a conduct which is not the same as that estimated for a bare frame. Additionally, partial openings inside infill walls are significant parameter prompting the seismic behaviour of infilled frames in this manner retreating lateral stiffness and strength. In this study is proposed to compare various models of buildings considering the openings (10% of surface area) at different locations in the infill walls for the seismic behaviour. A G+13 residential building is considered in Zone III with soil type II and analysis is carried out by Response Spectrum Method. Various parameters are considered such as Natural Time period, Base shear, Storey displacement, Storey drift and Storey stiffness were studied. The comparative study could simplify designers and code developers in selecting and recommending appropriate analytical models for estimating strength, stiffness, failure modes and other properties of infill frames with openings.
