Abstract:
The ABAQUS finite-element analysis platform was used to understand the mechanical behavior of concrete-filled steel tube reinforced concrete (CFSTRC) columns and steel reinforced concrete (SRC) beam plane frames under fire conditions. Thermal parameters and mechanical constitutive model of steel and concrete materials were reasonably selected, the correct boundary conditions were chosen, and a numerical model for the thermal mechanical coupling of CFSTRC columns and SRC beam plane frame structure was established. The finite-element model was verified from related experimental test results. The failure modes, deformation, and internal force distribution of the CFSTRC column and SRC beam plane frames were analyzed under ISO-834 standard fire conditions and with an external load. The influence of beam and column fire-load ratio on the fire resistance of the frame structure was established, and the fire-resistance differences between the plane frame structures and columns were compared. The CFSTRC column-steel reinforced concrete beam plane frame may undergo beam failure or the column and beam may fail simultaneously. The frame structure fire-resistance decreased with an increase of column and beam fire-load ratio. The column and beam fire-load ratio influence the fire resistance of the frames significantly. In this numerical example, the fire resistance of the frames is less than the single columns. It is suggested that the fire resistance of the frame structure should be considered when a fire-resistant structural engineering design is carried out.

Abstract:
Reinforced concrete buildings with shearwalls are very efficient to resist earthquake disturbances. In general, reinforced concrete frames are governed by flexure and low-rise shearwalls are governed by shear. If a structure includes both frames and shearwalls, it is generally governed by shearwalls. However, the ductility of ordinary reinforced concrete framed shearwalls is very limited. The experiments on framed shearwalls made of corrugated steel was recently reported. It was found that the ductility of framed shearwalls can be greatly improved if the thickness of the corrugated steel wall is appropriate to the surrounding reinforced concrete frame. If the thickness of the corrugated steel wall is too large when compared to the surrounding frame, the ductility will be reduced. It is shown in this paper that the fiber-reinforced plastic composites can be used to strengthen the critical regions of the reinforced concrete frames, so that the seismic behavior (including ductility and energy dissipation capability) is greatly improved.

Abstract:
This research work aims to compare the seismic performance (in terms of lateral load strength, stiffness, ductility, response modification factor and performance levels) of full scale infilled frames before and after retrofitting. To evaluate the seismic performance, two infilled frames with door opening at different locations were constructed in the laboratory based on the current construction practices in Pakistan. In one infilled frame, door opening was at the center (Frame-1) while in other, door opening was at a side (Frame-2). After construction, both the specimens were tested with quasi-static test. The damaged parent specimens were then retrofitted with Ferrocement overlay and cracks in the infill wall were repaired with grout injection. Steel door frames of gauge 18 were installed at the door opening to make the model more realistic. Results obtained after performing quasi static test on the retrofitted specimen have showed that the specimens not only gained the original strength, but the seismic parameters of the infilled frames were observed to have also improved.

Abstract:
AbstractBeam–column joints play an important role in providing lateral stiffness and integrity of frames during dynamic loading such as earthquake. In the high humidity areas, during functioning of the building cracks occur, which leads to the corrosion of the reinforcement due to the environmental exposures. Therefore, one of the main failures mechanism of building during an earthquake is caused by easily yielding of corroded steel reinforcement, which leads to reduce functionality of the frame joints in transferring the loads. This study proposed a new design to reinforce the beam-column joints with embedded carbon fiber-reinforced polymer (CFRP) rods, due to their extremely high strength and stiffness, along with the fact that they will not rust or corrode and very light weight. CFRP rods are used in reinforced concrete (RC) frame and ultra-high-performance concrete (UHPC) frame subjected to dynamic load. The prototype of the proposed design is constructed as frame with conventional concrete and frame with UHPC material to conduct experiments Test as well as numerical analysis to evaluate the performance of the proposed joints under dynamic loads. The results showed improvement in the performance of the frames reinforced with embedded CFRP in joints in terms of lateral load resistance capacity, ductility behaviour, overall stiffness, and failure mechanism.

Abstract:
Earthquake would cause unacceptable damage in reinforced concrete structures. In this paper, two retrofitting methods based on alternative load path are proposed for the reinforced concrete structure. One method is to add steel braces to the structure, and another one is to add tension cables to the structure. Pushover analyses for all frames are carried out using SAP2000. From the analysis results, steel braces or tension cables delay the formation of the first plastic hinge and failure of columns, and can better improve the seismic performance of reinforced concrete frame. The research results can be utilized for displacement-based seismic design and seismic performance evaluation of RC structures.

Abstract:
To study the influence of masonry infill walls on the hysteretic performance of reinforced concrete frames, a cyclic experiment was conducted for three two-story and two-span reinforced concrete frame structures, including one reinforced concrete frame without infill walls and two frames with infill walls. Whether the infill walls were constructed in the frames and the type of infilled material were the main parameters of the test. The major results reveal that: the infill walls clearly changed the mechanical mechanism of the frame structure at the early stage of loading, magnified the stiffness and horizontal bearing capacity of the frame structure, and enhanced the energy dissipation capacity of the frame structure, but reduced the deformation performance of the frame structure. In the later stage of loading, the infill walls would no longer work as one with the frame gradually with the failure of the infill walls, and the above performance of the structure would approach the empty frame structure. Moreover, the initial stiffness, energy dissipation capacity, and horizontal bearing capacity of the frame with infill walls of clay hollow bricks were the highest among the three specimens. But due to the strong diagonal bracing effect, the damage to the top of the columns and beam-column joints was serious, the yield displacement was reduced significantly, and the shear failure of the top of the columns and the joints occurred prematurely, which showed poor performance of deformation and ductility. However, the frame with infill walls of relatively soft aerated lightweight concrete blocks showed better performance of deformation and ductility.

The calculation results shows that at the bottom of the structure the stress and deformation is much larger than other parts with the action of constant load, live load and wind load. And with modal analysis and buckling analysis natural frequency and vibration mode are obtained to avoid resonance and predict the buckling load.

Abstract:
The basal theory of energy method is introduced, which makes use of the idea of energy balance to study the earthquake response of structures. Because of the high stiffness and low-cost of the steel frame-reinforced concrete shear wall hybrid structure, it is being widely used. But the study of the earthquake response prediction method of the structure has not been done yet. In this paper, energy method is used to study the earthquake response of the steel frame-reinforced concrete shear wall hybrid structure. A steel frame structure and a steel frame-reinforced concrete shear wall hybrid structure have been designed. The shear wall in steel frame-reinforced concrete shear wall hybrid structure is simplified as a column for easier study. In order to evaluate the results of the energy method, the time history analysis method is also used to study the earthquake response of the two structures. The shear coefficient, maximal interlaminar displacement and damage ratio of the two structures are studied. After comparison, it is found that the results of energy method and the time history analysis method are almost the same. The energy method can be easily used to study the earthquake response of the steel frame-reinforced concrete shear wall hybrid structure.

Abstract:
A controlled rocking reinforced concrete frame is a new type of vibration control structure system that uses resilient rocking columns and joints. The effects of earthquakes on this type of structure are reduced by weakening the overall stiffness, whereas the lateral displacement is controlled by the energy-dissipation dampers introduced into the structure. Two tests were performed for research: the reversed cyclic loading test and shaking table test. Two single-span single-story controlled rocking reinforced concrete frames were designed for reversed cyclic loading tests. These tests (i.e. a column-base joint stiffness test, beam-column joint stiffness test, and frame stiffness test) were performed under different conditions. The mechanical analysis model of the rocking joints was derived from the test results. With the parameters obtained from the cyclic tests, a numerical simulation method that established the analytical model of the controlled rocking reinforced concrete frame using the program ABAQUS is proposed, and the dynamic time-history analysis results of the controlled rocking reinforced concrete frame and of the conventional approach are compared to investigate the vibration control effect and seismic performance of the controlled rocking reinforced concrete frame. In addition, the inter-story drift could be effectively controlled by adding metallic dampers, and the shaking table test models of the controlled rocking reinforced concrete frame with metallic dampers were designed and constructed. The comparison of the results of the numerical analysis and the shaking table test demonstrates that the model building of the controlled rocking reinforced concrete frame structure is efficient and that the controlled rocking reinforced concrete frame exhibits an excellent seismic performance.

Abstract:
This article mainly focused on the seismic performance of steel reinforced recycled concrete frame structure under low-cyclic reversed loading. To evaluate seismic performance of steel reinforced recycled concrete frame structure, a two-span three-storied steel reinforced recycled concrete frame was conducted at civil engineering laboratory of Xi’an University of Architecture and Technology. Experimental and numerical studies were implemented to investigate the crack status, failure modes, hysteresis loops, skeleton curves, energy dissipation capacity, load–displacement curves, P-Δ effect, and the influence of recycled concrete strength under low-cyclic reversed loading. Results indicate that the steel reinforced recycled concrete frame structure has good seismic behavior during test, and the spindle-shaped hysteresis loops illustrate that the frame has relatively high energy dissipation capacities. The design of steel reinforced recycled concrete frame satisfied the requirements of strong column weak beam, strong shear weak bending, and strong joint weak components. Finally, the simulated results obtained by OpenSees software agree well with the test, which verify the rationality and reliability of the proposed model. The conclusions of this article will be helpful for the design of steel reinforced recycled concrete structures in seismic regions.

Abstract:
This paper presents the reliability analysis of the frame structures with semi-rigid connections. For this purpose, the SEMIFEM finite element program that is capable of dealing with the semi-rigid connections is coded in FORTRAN. Then, this program is connected to the reliability algorithm. The direct coupling method, which is a combination of the reliability method and finite element method, is utilized to determine the reliability indexes and probabilities of failure for the structure. The first order reliability method (FORM) is the one favored in the present reliability analysis. Two sets of steel framed structures are analyzed; each of four and eight stories, consisting of a portal frame and three types of concentrically braced frames. Concrete compression strength limit state in reinforced concrete (RC) columns, steel strength limit state in steel braces and inter-story drift limit state are considered in reliability evaluation. According to the limit states, X braced frames are determined as the safest structures, while the portal frames are regarded as the most unsafe structures. As the connection percentage increases, the safety of the structure increases in terms of inter-story drift and steel strength limit states, but decreases for concrete compression strength limit states.

Abstract:
Infill panels are usually used in structures; therefore, it is very important to study their behaviour and their influence on bare frames. Several models had been proposed to understand the effect of the infill panels on structure. The aim of this work is to identify the effect of the presence of infill panels on bare frames. The diagonal stiffness and shear compression failure of the structure, the nonlinear behaviour of the infilled frame under axial loading and the relation between the strength, ductility and stress-strain of different previous experiments will be presented. Experimental research on the interaction between the steel frames and infill panels has been done to determine the behaviour of steel frames with different types of infill walls. Many frames with composite panels subjected to cyclic-loading were realized to determine the damping ratio, the static and dynamic response, strength and stiffness degradation of infill elements. The objective of this paper is to represent and analyze the hysteretic behaviour, failure modes, and the variation of different parameters of the infilled bare frame like stiffness, strength, ductility and loading displacement curves.

The results of experimental and theoretical researches of crack resistance, development and growth of cracks of a fragment of a reinforced concrete multi-storey frame of a monolithic building with prestressed beams for a special emergency impact caused by a sudden removal of one of the load-bearing elements are presented. Removal of the middle column of the frame was considered as an emergency impact. Analysis of the pattern cracking in the frames with a prestressed beam before and after a special impact is carried out against the pattern cracking in an unstressed frame structure. Based on the increments of cracks width in the beam, the coefficient of dynamic additional loading in prestressed frame structures from a special impact was calculated. The obtained results of experimental and theoretical researches of the crack resistance of frame structures in considered influences can be used in the development of methods for protecting the frames of monolithic multi-storey buildings against progressive collapse.

Abstract:
This paper is the first of two companion papers on the evaluation of the level of protection offered by ductile and nominally ductile reinforced concrete structures in Canada. In this paper, the seismic behaviour of two half-scale reinforced concrete moment resisting frames is investigated by shake table tests. In the second paper, the experimental results obtained from the shake table tests are compared with the results generated from inelastic time-history dynamic analyses. Each frame had two bays and two storeys with overall dimensions of 5 m in width and 3 m in height. The first structure was designed as a ductile frame according to current Canadian standards; and the second structure incorporated only nominally ductile details. Two levels of intensity were retained for the historical ground motion used in the tests. The first level was representative of the design earthquake considered; the amplitudes were doubled for the second intensity. The ductile structure performed well during both tests. The frame with nominal ductility performed well during the first test, but was on the verge of collapse after the second test. Based on these experimental results, recommendations are presented to harmonize the seismic protection of ductile and nominally ductile reinforced concrete frames in Canada.Key words: moment resisting frames, earthquakes, reinforced concrete, seismic, shake table.

This paper mainly studies the effect of cast-in-situ phosphogypsum on seismic behaviour of reinforced concrete grid frame. The mechanical behaviour of three reinforced concrete grid frames and four cast-in-situ phosphogypsum-reinforced concrete grid frame composite walls under low cycle alternating load was designed and tested. The test results show that the reinforced concrete grid frame has less bearing capacity and poor energy consumption. The addition of cast-in-situ phosphogypsum can effectively improve the seismic behaviour of the reinforced concrete grid frame. Compared with the reinforced concrete grid frame, the bearing capacity of the cast-in-situ phosphogypsum-reinforced concrete grid frame composite wall is increased by 2-3 times, the displacement ductility coefficient is increased by 0.95∼1.2 times, and the relative accumulative energy consumption is increased by 86%∼216%. This shows that the composite wall has better bearing capacity, ductility, and energy dissipation capacity.

Abstract:
A variant of the crack resistance criterion and the strength criterion of plane-stressed structures made of high-strength fiber-reinforced concrete, fiber-reinforced concrete is proposed. The criteria are based on the theory of plasticity of concrete and reinforced concrete G.A. Genieva. In general, the condition for crack resistance of a plane-stressed fiber-reinforced concrete element is presented in the form of an ellipse with jumps on the coordinate axes of the main reduced stresses. The strength condition of a fiber-reinforced concrete element is described by a complex figure that takes into account cracking in the element under a plane stress state. The characteristic points on the coordinate axes are calculated from the physical and mechanical characteristics of concrete strength, obtained as a result of testing high-strength fiber-reinforced concrete for uniaxial compression and uniaxial tension with “dissolved” fiber in the concrete body and reinforcement reduced to concrete. The results of a comparative analysis of the criteria for crack resistance and strength of high-strength concrete and high-strength fiber-reinforced concrete are given, depending on the percentage of fiber in the concrete body and the type of fiber used. The proposed analytical dependences can be used to analyze the crack resistance and strength of plane-stressed reinforced concrete beams-walls reinforced with fiber, corner zones of shallow shells and other plane-stressed structures made of high-strength fiber-reinforced concrete and fiber-reinforced concrete.

Abstract:
Masonry infilled walls are widely used in reinforced concrete (RC) frams worldwide. However, infilled RC frame building failure is a common mode in destructive earthquakes. Further researcher is needed to bring insightful understandings into the behaviors of these structures. Therefore, this study investigates seismic parameters, ultimate tensile damage, and force transfer mechanisms in a reinforced concrete structure under in-plan load. For this purpose, the definitions and the relevant literature were reviewed. Then, an analytical software supporting an infill model was selected and described altogether with a particular modeling approach. Calibrating software results with those presented by Abdulhafez et al. (2014), the researchers designed a series of planer one-story one-bay reinforced concrete frames upon ACI 318M-14 Building Code. The seismic behavior of infilled frames were also studied using finite element method. Force transfer mechanisms in infilled frame with opening, which is one of the important items, was investigated in this study. Comparing the analysis outcomes with the bar frame, it was indicated that the ultimate load, stiffness, and toughness of the full in-filled frame were increased while the ductility was decreased. It was also revealed that the presence of opening in infilled frame decreased the ultimate load, stiffness and toughness corresponding full infilled frame. In addition, the increasing of opening size increased the reduction of the ultimate load, stiffness and toughness.

Two full scale frames were tested on a shaking table to investigate seismic performance and fracture mechanism of fiber reinforced concrete in contrast to the plain concrete. The information about acceleration response, the maximum strain value as well as the time to reach it, the typical strain - time curves and the crack development of two test frames were presented. Test results indicate that reinforced concrete did not crack during the test; the fiber reinforced concrete could better absorb or consume energy in the process of stress redistribution after peak acceleration; maximum strain and maximum acceleration did not occur at the same time; structure came into being deformation even failure when the seismic energy in the structure gone up to certain extent, and the dynamic failure would be their main failure modes.

Abstract:
Structure under long-term load, environmental erosion, material aging, especially under the seismic action can cause damage accumulation and bearing capacity decrease. In order to make sure its safety and reliable, avoid extreme cases of catastrophic accident, it is necessary to carry out the engineering structural health diagnosis. Using SAP2000 software, seismic response analysis for a two layer reinforced concrete frame structure is carried out. The laws of the acceleration response time history and spectrum under different seismic action were found out by discussing structure in no damage and different damages. The results showed that no matter where the damage located, the top node response increment is bigger than the middle node, the peak of acceleration response spectrum changes little with the beam damage degrees changing. Selecting the acceleration response peak of the top node as a structural damage index is feasible in the damage detection and identification of engineering structures, but analyzing the response spectrum for damage detection is unpractical.

Abstract:
Concrete-filled steel tubular structural members can be recognized as an effective mean to improve the mechanical behavior in terms of strength, stiffness, ductility, and energy dissipation for the initial recycle aggregate concrete deficiencies compared with natural aggregate concrete. A small-scale model of square concrete-filled steel tubular column–reinforced concrete beam frame realized employing 100% recycled coarse aggregates was tested under combined axial loads and cyclic reversed lateral flexure. The failure modes, plastic hinges sequence, hysteresis loop, skeleton curve, stiffness degeneration, energy dissipation capacity, and ductility of the frame were presented and analyzed in detail. The structural behavior of square concrete-filled steel tubular column–reinforced concrete beam frame with 100% recycled coarse aggregates was compared with circular concrete-filled steel tubular column–reinforced concrete beam frame made with 100% recycled coarse aggregates. A fiber-based program model for the nonlinear analysis of concrete-filled steel tubular column–reinforced concrete beam frames incorporating recycled coarse aggregates was developed using SeismoStruct, to highlight the effect of recycled coarse aggregate content on mechanical behavior of recycled aggregate concrete and the confinement effect provided by outer tubes on core concrete. The analysis results show that the numerical model can well simulate and predict the seismic behavior of concrete-filled steel tubular column–reinforced concrete beam frames with 100% recycled coarse aggregate content. Both experimental and numerical results demonstrate that concrete-filled steel tubular column–reinforced concrete beam frames with large content of recycled coarse aggregates have a receivable seismic performance, and it is feasible to apply and popularize recycled aggregate concrete into concrete-filled steel tubular structures in seismic regions.

Field measurements of dynamic characteristics of the multi-storey reinforced concrete frame structure buildings were carried out, by using the ambient vibration test technique, and structural modal parameters were extracted. The measured results and calculated results in accordance with current design specifications were compared. Results show that for multi-storey reinforced concrete frame structure, the measured vibration period of structure is close to the natural period calculated in accordance with the empirical formula of the “Load Code for the Design of Building Structures”. In the actual project, when the designer calculate the natural period if considering only the quality of the infill walls, without considering the stiffness of the infill walls, the period should be shortened. In this paper, the recommended period shortening factor for the multi-storey reinforced concrete frame structure is gave 0.4~0.5.

Abstract:
This paper concentrates on the fragility analysis method for vertically plan reinforced concrete frame structures. The weakness story inter-story drift ratio is selected as the fragility variable for vertically plan structures. Five states are established to distinguish the structural seismic performance levels, which are expressed with inter-story drift ratio. Then through the nonlinear dynamic analysis and linear regress, the exceeding probability function of seismic response is obtained and a new fragility analysis method is put forward for vertically irregular frame structures. Two kind of unit models, two kind of hysteretic models and forty earthquake records are chosen to established structure-earthquake system samples. Thus one hundred and twenty structure-earthquake system samples are obtained for irregular reinforced concrete frame, which take into account the uncertainty of member materials, structures systems, numerical simulation models and earthquake motions adequately. Then example is presented to demonstrate the applicability and utility of the proposed methodology. Seismic performances of a vertically irregular reinforced concrete frame structure are evaluated in detail. It is concluded that fragility curves are more abrupt in low input earthquake motion intensity and they are influenced much by the structural performance levels.

Abstract:
In the design of multi-storey frame structures, there is a question of a proper evaluation of the stiffness of reinforced concrete frame joints. This problem is very important especially in the case of structures subjected to seismic load, where the forces act repeatedly. Concrete is able to carry the compression stresses and partially the shear stresses. The tension stresses can reach only low level. The maximum tension stresses (tension strength) obtained from simple tension test of the concrete are not the same as the maximum tension stresses in the reinforced concrete. The shear stiffness is the matter of the width of the concrete cracks. To improve the knowledge in this field, the experimental verification of the reinforced concrete frame joint had been arranged.

Abstract:
The intersections between beams and columns in a reinforced concrete building structure are called frame joints. It is a region with significant bending stiffness but subjected to large shear stresses. Appropriate modeling of the flexibility of reinforced concrete frames is essential to its design, in service limit states as well as in ultimate limit states. It has been shown, theoretically as well as experimentally, that the influence of joint flexibility may account for 20% of total structural lateral displacement. Models using only bar elements and rotational springs are proposed to consider the joint flexibility in linear analyses of building structures. In order to validate the proposed model, comparisons with experimental results found in the literature are made. Finally, the results of second order analyses using the proposed model are compared with those obtained by finite elements.

Abstract:
In the era of big data, the efficient use of idle data in reinforced concrete structures has become a key issue in optimizing seismic performance evaluation methods for building structures. In this paper, based on the evaluation method of structural displacement seismic performance and based on the characteristics of high scalability and high fault tolerance of the cloud platform, the open source distributed and storage features of the Hadoop architecture cloud platform are introduced as a subproject of Apache Nutch project, Hadoop cloud platform. With features such as high scalability, high fault tolerance, and flexible deployment, the storage platform is secure, stable, and reliable. From the evaluation of the seismic performance of newly-built buildings and existing damaged buildings, according to the structural strength-ductility theory of the structure, the building structure resists earthquakes with its strength and ductility and buildings are divided into four categories. Due to the influence of time or seismic damage on the structure of reinforced concrete frame structures, their material properties are often deteriorating. Using the distributed computing design concept to efficiently process big data, a dynamic evaluation model for the seismic performance of reinforced concrete frame structures is established. A project of a 10-story reinforced concrete frame structure was selected for calculation and analysis; the engineering example was used to verify the accuracy and efficiency of the model, and the seismic performance of the floor was analyzed. It can be seen that the initial stiffness index of the structure is not sensitive to the damage location of the structure. The platform based on the concept of distributed computing big data processing can effectively improve the efficiency and accuracy of the evaluation of reinforced concrete frame structures.

Abstract:
Reinforced concrete buildings with masonry infill are vulnerable in earthquakes primarily because the masonry walls often fail due to out-of-plane forces and can trigger soft-story collapses. In order to prevent these failures, many engineers in the Caribbean have partially reinforced the infill walls and connected them to the reinforced concrete frame. This forms a hybrid concrete-masonry structure. Hybrid concrete-masonry structures have the potential to improve the seismic performance of many structures across the globe, as they are an easy adaptation from traditional unreinforced masonry infill. However, there is little codified guidance for this type of structure, and the influence of the masonry infill and dowel connections on the in-plane behavior of the frame is often neglected. This paper summarizes the current design and construction practices for hybrid concrete-masonry structures and assesses their seismic performance via cyclic tests on full scale test specimens. Based on the results of the experiment, a method is proposed to account for the dowel connections and the partially reinforced infill when designing hybrid concrete-masonry structures in earthquake zones.

Abstract:
Since structural damage by fire in modern Reinforced Concrete (RC) structures causes significant loss of human life and property, it is important to evaluate the residual capacity of fire-damaged RC structures exposed to high temperatures. In this study, the behavior of fire-damaged RC frame structures (single-bay & three-bay frame), considering non-mechanical strain, was investigated by applying numerical analysis. The behavior mechanism was analyzed by numerical results of the single-bay frame and similar behavior was observed in each member of the three-bay frame. Principally, regarding the three-bay frame structure, the time of fire-resistance was evaluated under various fire scenarios, which included symmetrical and asymmetrical fires within the structure. The results of numerical analysis showed that, as the story load action on the structure increases, the fire-resistance time decreases. Finally, asymmetric fires should be considered for safety assessment against fire because the fire-resistance time under asymmetric fire conditions is shorter than that under symmetric fire conditions for all load conditions.
