City image includes people's perceptions of the built and natural environments as well as the emotions and ideas the city arouses in them. In the city image, the preservation of the buildings, especially historical buildings, which carry the past cultures, meaning and structural features of the city to the present day, can be ensured by making these buildings visible and perceptible by the inhabitants. Historical buildings' visibility can facilitate the recognition and appreciation of their historical significance, thereby contributing to the preservation of the city's cultural heritage. This study aims to analyse the visibility of a historical building that holds a significant place in the urban memory and to suggest recommendations for enhancing its visibility. In this context, the viewpoints used to examine the İskenderun Beş Temmuz Primary School Historical Building’s visibility were specified by space syntax visibility graph analysis (VGA). Subsequently, the building's visibility in three different historical periods was determined by the isovists technique, utilizing these viewpoints. Based on the same viewpoints, an observational field study and a survey applied to 47 people were conducted. Consequently, it was identified that the historical building could not be sufficiently seen due to the presence of surrounding service structures, perimeter walls, and high buildings. Furthermore, this study proposed the removal of additional structures that negatively affect historical building's visibility. Additionally, a design approach was developed for new buildings and landscaping to enhance the historical building's visibility, and the efficacy of the proposed design was evaluated through isovists and VGA analyses.

Abstract Today’s cities are developing at a breakneck pace, resulting in physical modifications to buildings. This growth can also be witnessed in the presence of new structures designed to house city-related operations. This research was conducted in the corridor area of Surabaya’s Karet Street, a historical district. Numerous historical structures may be seen along Karet Street, including surviving colonial and Chinese-style structures. Historically, this Karet Street corridor region served as a commerce hub due to its proximity to the Kali Mas (Mas River) trade route. However, as the era progressed, the buildings in the corridor of Karet Street became abandoned, many were neglected, and other structures were added, resulting in inconsistency between buildings. Thus, this research aimed to characterize the building facade components along the Karet Street corridor. The research technique used was descriptive qualitative research. Sixty-two structures along the Karet Street corridor comprise the sampled area. The factors consisted of the building’s door/entrance, windows, walls, roof, and the stylef the building—a qualitative descriptive analysis based on the state of the building’s facade in the field. Direct observation, existing literature, and documentation were employed to obtain data. The study’s findings revealed inconsistencies in the building’s exterior components, particularly in the structure’s modern style. In an area that contains colonial and Chinese-style buildings, this contradiction might undermine the area’s historical assets. Additionally, modifications and damage to facade components might obliterate the authenticity of existing historical value.

Buildings in Europe, account for about 20–40% of total final energy consumption. Therefore reduction of energy demand is crucial. It has become one of the most important issues to achieve energy saving at installations and refurbishments of buildings. Humidity in the wall structure of buildings produced by precipitate and other circumstances could modify the building’s heat capacity, the heat transfer coefficient furthermore density and/or other factors. In this study, wall structures of buildings with nearly zero net energy consumption were examined that were built from different materials with different moisture load. By applying different experiments and calculations we presented the changes of the stored heat energy of different wall structures in relation to the duration of the wetting time. The external wall of the building is the interface between the interior of the building and the outdoor environment. From the perspective of sorption and heat capacity, knowledge of the behavior of structures in relation to their moisture content, can help us to select the perfect type of wall. We have found three major traits peculiar to the change in the stored heat of different building structures in relation to the moisture load.

Abstract The paper brings to attention the industrial buildings from the 1900s through two case studies of high-rise buildings for the period in which they were built. The study is done by analyzing the resistance structure of two buildings built around the 1880s and their behavior over time. The destiny of these very valuable buildings from a historical, architectural and structural point of view is regarded as a motivation for the authors for the elaboration of the present paper. One of the studied buildings has been dismantled, while for the second one, the owners are allocating funding for structural rehabilitation in order to maintain it, in parallel with the re-conversion, modernization and expansion of the building. For valuable buildings and historic monument buildings, maintenance activity is particularly important in order to prevent structural degradation. It is especially important to pass on the historical legacy to future generations, therefore its structural strengthening and rehabilitation must take precedence over financial implications.

In the conditions of rapid scientific and technological progress, the technologies development pace of designing buildings and structures began to outstrip the practical application of them in the domestic market in comparison with the countries of the western world. Ukrainian building design tools have ceased to be internationally competitive. In these circumstances, it is especially important to introduce new and improve existing methods and tools for modeling buildings and structures. An important task for a modern designer is the ability to use a computer model at various stages of the building's life cycle, namely: design, construction, operation. To solve this problem, one can apply a new design method - Building Information Modeling (BIM). The purpose of this research is to explore the possibilities of using information modeling technologies for buildings as a means of their life cycle managing. The scientific and practical importance of the work stands in the possibility of introducing of information modeling technologies of buildings not only as a new design method, but also as a means of managing of the life cycle of the building at all its stages. The results of the research are based on the analysis of literary sources and practical experience of the authors. The article revealed the possibility usage of building information modeling as means of managing of the life cycle of building and structures. There is considered options and the main problems of information modeling application on different stages of buildings life cycle. In this paper, the main functions of building information modeling, which are necessary for managing of the life cycle of buildings and structures, have been analyzed and formulated. The practical importance of the results of this paper is in the presentation of the proposed functions and development prospects of building information modeling tools.

The article provides an analysis of existing computational practices for solving the problems of survivability of structures of buildings and structures. The issues of progressive collapse of buildings under the influence of seismic loads are considered separately. It is noted that in order to ensure the reliability of the structures of buildings and structures under special impacts, it is necessary to have a clear regulation in the system of regulatory documentation of the Russian Federation. Most calculations for progressive collapse are made for frame buildings. In this paper, one of the approaches to solving the problem of survivability is proposed on the example of calculating a multi-storey building of a wall structural system for progressive collapse with a sequential failure of the most loaded walls of the first floor. The change in the stress-strain state of the building's load-bearing structures with successive failure of the walls of the first floor at each stage of the calculation is shown.

Employing twisted forms in tall buildings is a relatively new architectural phenomenon, as are the cases with the Chicago Spire and Shanghai Tower. These super-tall buildings employ outrigger structures as their primary lateral load resisting systems. This paper presents structural performance of outrigger structures employed for twisted towers. Twisted tall buildings of different twisted rates are designed with outrigger structures. Two cases are studied comparatively. The first case uses spirally slanted perimeter mega-columns in response to the twisted building form. The second case uses vertical mega-columns, set back from the building perimeter, and cantilevered floor slabs from the column lines. The comparative structural efficiency of these cases is presented.

The number of high rise building has increased significantly as supporting infrastructure in many big cities in Indonesia. Most of the high rise buildings in Indonesia are constructed using reinforced concrete (r/c) moment resisting frame systems. However, due to the high seismicity of many of the regions of Indonesia, the use of moment resisting frames as single system, especially for tall buildings, are restricted. This structural system is in general quite flexible, and therefore excessive lateral drifts are experienced under seismic forces. In practice, adding buckling restrained brace (BRB) can be used to limit the lateral drift in high rise buildings. The objective of this paper is to present a study on the use of BRB elements in high rise r/c frame buildings to evaluate their seismic performance. In this paper, a 20 story office building located in a high seismicity region is modeled into two basic distinctions, i.e. building with BRB and without BRB. The adopted system of BRB is UBB (Unbonded Brace) type. The seismic response of the buildings is obtained by conducting non-linear time history analysis with seven scaled ground motions. Then, the performance of these buildings are evaluated and compared. Based on the findings, some recommendations are proposed for the use of BRB in the design of high rise r/c frame buildings located in regions with high seismicity.

Tall building developments have been rapidly increasing worldwide. This paper reviews the evolution of tall building’s structural systems and the technological driving force behind tall building developments. For the primary structural systems, a new classification – interior structures and exterior structures – is presented. While most representative structural systems for tall buildings are discussed, the emphasis in this review paper is on current trends such as modeling and analysis. Consideration of site specific lateral loading due to wind or earthquake loads along with vertical gravity loads is important for finding the behavior of the tall buildings. The design of tall buildings essentially involves a conceptual design, approximate analysis, preliminary design and optimization, to safely carry gravity and lateral loads. Analysis and design of buildings for static and dynamic forces is a routine affair these days because of availability of affordable computers and specialized programs which can be used for the analysis. Finally, the future of structural developments in tall buildings is envisioned briefly

Public buildings are structures used to serve the activities of the community at large. These buildings become gathering places for many people at one time. As venues for community activities, the presence of public buildings in tsunami-prone areas can increase vulnerability for their users. Therefore, it is necessary to understand the characteristics of public buildings located in regions at risk of tsunamis. This study aims to determine the reliability of public buildings based on the distribution of building zones, building structures, building heights, and the orientation of building locations. The results show that there are 328 public building units spread across the study area, which have varying levels of tsunami risk from low, medium, to high. The percentage breakdown of building classifications includes government buildings (31.1%), educational facilities (40.5%), health services (6.1%), places of worship (17.1%), commercial buildings (2.1%), and other facilities (3.0%). In terms of zone distribution, public buildings are predominantly located in alert zones that have a high risk of tsunami disasters. The building structures are generally permanent, made of reinforced concrete, with the majority being two or three stories high. The buildings are distributed across sparse, medium, and dense locations. Buildings with good reliability characteristics, such as strong structures resistant to tsunami waves and medium to high building heights, can be considered as alternative vertical evacuation sites for tsunamis. In Banda Aceh, public buildings are mostly low-rise, while medium-rise buildings include office and health service buildings. To ensure safety and security, it is necessary to enhance the quality of public buildings in the future, especially in areas with high tsunami risk.

Some prototype design solutions are not verified whether the tests, by good computational analysis or verification of long-term use of the building. In the context of changing standards in building design, new approaches are needed. If in wooden buildings the potential risk of fire is higher than other buildings, we need special methods, materials and practical skills.

Objective. In this paper, buildings of various shapes that have high seismic resistance are considered. Such seismic resistance is provided by the rational shape and outlines of the building itself. Here, the influence of the torsion of the building in the plan is minimized, thereby eliminating large stresses at the ends of the designed building. At the same time, the translational movement of the building in the plan is preserved.Method. By optimizing the shape and shape of buildings for various purposes, high efficiency of the structure is ensured under seismic effects. By comparing the shape and outlines of various buildings, the best variant of their layout is selected.Result. Structural schemes of buildings and structures with high resistance to seismic effects are given. A comparative analysis and recommendation for the design of earthquake-resistant buildings are given. Structural schemes for buildings and structures of various outlines have been developed: round, square, rectangular; constructive schemes of volumetric seismic-resistant structures, pyramidal, conical of various shapes, have been drawn up. Recommendations for the design of earthquake-resistant buildings and structures with optimal geometric shapes are made.Conclusion.The design schemes proposed in the article can be used in the design of earthquake-resistant buildings and structures for various purposes.

In 2011, the Heisei Tsunami (also known as the East Japan Tsunami) caused unprecedented damage to well-engineered buildings and coastal structures. We examine two reinforced concrete buildings that were exposed to similar tsunami loadings, but one collapsed and the other did not. It is shown that the contrast is partly resulted from the presence of a building foundation that could cause a time delay and attenuation of the buoyancy effect on the buildings. The surviving building must be stabilized by the weight of water that flooded the building interior. We also investigate failure patterns of concrete seawalls and coastal dykes. It is demonstrated that flow-induced suction pressures on the crown play a role in the failure of concrete panels that covered the dyke’s infill. High-speed flows together with high compressing pressures can cause the formation of a scour at the leeside foot of the dyke. Considerations for the design guidelines for buildings and coastal structures to cope with the “beyond-the-design-basis” extreme coastal hazards are proposed.

The article analyzes modern methods for monitoring the technical operation of buildings and structures. Technical inspection of buildings and structures is a separate type of construction activity. The necessity for a technical survey is caused by the physical and moral deterioration of building structures and changes of terms of use, as well as the absence in building codes of an explicit account of the time factor. Ensuring the operability of structures at a specific moment of existence requires a set of measures that differ from the design, manufacture and installation of building elements associated with the creation of normal conditions for the life of enterprises in industrial buildings and structures and, above all, the safety of the operation process.
Specialists in the technical operation of buildings and structures have new tools for more accurate determination of defects and supervision of buildings and structures. The emergence and development of IT technologies, in particular, the use of mathematical, computer modeling techniques have demonstrated unprecedented opportunities for a comprehensive approach to testing the performance of buildings. Most modern methods of technical inspection of buildings do not require significant financial and labor costs; they can be directly implemented both during the planning of the facility and during its operation without reducing the bearing capacity of structures, unlike classical methods (visual, visual-instrumental, etc.). Their goal is to control the technical condition of building structures and early diagnosis of threats to the existence of the object. The integrated use of these methods at different stages of the life cycle of buildings will increase their service life and the comfort and safety of staying in them.

The modern building technologies are technologies of green construction, near zero-energy and active buildings with bioclimatic design, optimized energy consumption and CO2 emissions. Prospective enclosing structures of such buildings are structures using available, low cost, and environmentally friendly materials based on plant raw materials. In this paper the evaluation of technical solutions of wall enclosing structures using flax concrete based on lime binder with a density of 300-350 kg/m3 was carried out, taking into account their heating and cooling loads in residential buildings. It is shown that the provision of the necessary indicators of the external walls of energy-efficient buildings is achieved by using multilayer structures with a heat-insulating layer of flax straw concrete or a single-layer structures made from flax straw concrete in frame construction technology.

Full textAbstract:
Vibrations are one of the main environmental elements that influence buildings and mechanical structures, potentially shortening their lifespan. Taller, lighter, more flexible structures are required by current trends in the construction sector, yet they have relatively low damping values. This raises the likelihood of failure and causes issues with serviceability. If the frequency of excitation coincides with one of the inherent frequencies of the system, many building structures and bridges will collapse due to vibration. Today, a variety of techniques are available to reduce a structure's vibrations. One of these is the idea of using a tuned mass damper, which has become popular recently. In this paper a study has been investigated which is on the behaviour of tall building when it is equipped with Tuned Mass Damper. It is observed that buildings with Tuned Mass Damper are more resistant to seismic vibrations compared to the buildings without Tuned Mass Dampers.

The article discusses the monumental buildings of Bilyar, located in the citadel of the fortified settlement. Great mosque of Bilyar and other public buildings were investigated in the 70s of XX century. At the same time their reconstruction, which became canonical were made. Consideration of Bilyar buildings in the context of the architecture of the entire Muslim world makes it possible to make some adjustments both in the interpretation of buildings and in the elements of their reconstruction. The building with underfloor heating near the Juma mosque was considered the house of a feudal lord and was reconstructed as a two-story domed building. Another multi-room building with heated floors was interpreted as a caravanserai. Underfloor heating, plastering floors and walls with a water-resistant mortar, and a water drainage system indicate that these buildings were public baths. Like all eastern baths, they had one floor and were multi-domed buildings.

Diagrid structures are widely used for today’s tall buildings due to their distinguished architectural aesthetics in any existing urban context and structural efficiency in carrying lateral loads. With prevalent emergence of complex-shaped buildings throughout the world, this paper investigates structural efficiency of diagrid structures employed for complex-shaped tall buildings, such as twisted, tilted and freeform towers. For each complex form category, tall buildings are designed with diagrid systems, and their structural efficiency is studied in conjunction with building forms. In order to investigate the impacts of various important geometric configurations of complex-shaped tall buildings, parametric models are generated using appropriate computer programs, and the models are exported to structural engineering software for design and analyses.

The article substantiates the relevance of the design and construction of buildings and structures of the Ukraine population civil protection in the conditions of possible shock-explosive influences. The aim of the work is to systematize information about the impact of explosive loads on building structures and develop recommendations for improving the stability of buildings and civil protection structures.The influence of shock wave during the detonation of explosives on the structures of buildings is considered and systematized. The features of distribution of pressure of blast wave on the structures of buildings in time, depending on magnitude of their distances to the epicenter of the explosion, are analyzed. The features of the influence of blast wave, which expands from the source of detonation, on low-rise buildings with flat roofs and the sequence of development of deformations and destruction of their structures at three stages of wave propagation are revealed. The nature of the influence of blast wave on multi-storey and high-rise buildings and the sequence of development of deformations and destruction of their structures are analyzed. Examples of destruction of structures of buildings of various structural systems from explosions are given.The paper gives recommendations for design of blast-resistant buildings with built-in bomb shelters that are able to resist explosive loads without progressive collapse, which leads to a cascading sequence of damage to adjacent building structures. The ways of redistribution of gravitational loads on the structural systems of buildings and structures are analyzed, recommendations are made for design of explosion-proof buildings.Conclusions are drawn about the feasibility of using monolithic reinforced concrete frames, which are able to plastically deform, redistribute loads and resist the onset of progressive collapse, which leads to appearance of a cascading sequence of damage to adjacent building structures.

It is possible to ensure safety of the entire construction process as well as safe operation of buildings and structures in future by timely implementation of geotechnical monitoring. Geotechnical monitoring of buildings and structures is a complex research of “soil base – foundation – above ground structures of a building”. Geotechnical monitoring studies behaviour of buildings and structures during construction and operation and, safety measures to prevent hazardous situations in future are undertaken upon analysis of acquired results. Geotechnical monitoring comprises combination of works, including field observation for structures’ behaviour of a building under construction or renovation, its foundation, including soil body surrounding the structure under construction, and field observation for structures of surrounding buildings. Such monitoring allows us to timely detect and prevent non-reversible processes that occur in “soil base – foundation – above ground structures of a building” system. Considering task in hand to ensure safety and security of buildings and structures, list of geotechnical monitoring works can be divided into following blocks: object monitoring; hydrogeological monitoring; ecological monitoring and computational and analytical block which makes assessment of current geotechnical situation on the construction object and develops relevant recommendation for further continuation of works. This article looks into special aspects of multiyear (2005 – 2019) geotechnical monitoring for deformational behaviour of buildings under operation, open parking spaces No.1 and No.2, located in area of effect from construction of railway connecting Vnukovo-1 airport and Kievskiy train station in Moscow and in the area of effect of new Vnukovo-1 airport construction. Article looks into tasks to ensure regular operation of existing buildings and monitoring of hazardous situations and their origin caused by construction works or poor technical condition of monitored objects. Particular to renovation of Vnukovo-1 airport, that started in 2005 is the fact that during construction it was necessary to ensure operation of a number of maintained buildings. Among them are open parking spaces No.1 and No.2.

Seismic isolation systems have been recognized for their effectiveness in protecting building and their contents. Despite costly technology, seismic isolation has been used in several countries, including Japan. Base-isolated building response could be substantially reduced, which is very favorable compared to conventional fixed-base buildings. Several studies have focused on base-isolated building response and the effects of isolation properties, for example, but none has talked about performance in ways that nonengineers such as building owners could understand. The slight damage from an earthquake may protect a building’s structural integrity, but it may also damage nonstructural components and disrupt ongoing building functionalityCF. The PEER methodology framework used to considerCFdamage to nonstructural components uses a nonstructural component fragility curve, taking into account building location, and produces results in the form of a return period, in years, indicating how long the building may be expected to exceed that specified damage state. Several building structures are investigated and discussed.

Abstract The key task of the building design is the comprehensive elimination of hazards arising from various impacts on buildings, including seismic ones. Recently, new structural systems have been developed to ensure the earthquake resistance of buildings, as well as the already known ones are being improved. One of the types of structural systems that can be used in seismically active areas are buildings with suspended structures. There are many design solutions for buildings with suspended structures that differ in the type of supporting structure, suspension system and geometric shape. The possibility of using suspended structures under dynamic influences is explained by a load decrease in the load-bearing elements of the building due to the flexibility of these structures, as well as a large natural period of oscillations of buildings with suspended structures. Some aspects of the use of buildings with suspended structures are not fully understood, which prompted a study of the behavior of these buildings using various structural solutions in earthquake conditions. For the effective use of these structures in the practice of earthquake-resistant construction, an important issue is to understand the behavior of suspended structures under seismic influences of a wide frequency spectrum. The results of the study are presented in the paper.

Abstract Indonesia is located at the confluence of three main tectonic plates which makes it one of the countries with the highest earthquake risk in the world. Recorded experiences has showed that the earthquake cause damage to buildings particularly multi-storey building structures. The purpose of this study is to determine the performance level of multi-storey reinforced concrete structures using a performance-based design method based on the ATC-40 and FEMA 440 regulations. The buildings in this study are 4-storey and 8-storey buildings. The effect of column size, beam size, and concrete quality are investigated. This study results the performance level, capacity curve, level of effectiveness of variations based on pushover analysis using the ATC-40 and FEMA 440. It can be concluded that the building structure is considered as Operational category based on the ATC-40 and FEMA 440 regulations. On the other hand, for the level of effectiveness of variations in building structures, it is more effective to enlarge the column cross-sectional dimensions and increase the height of the beam for 4-storey and 8-storey buildings, respectively.

Full textAbstract:
The destruction of buildings and structures occurs as a result of natural disasters, accidents, or terorist attactacts which in many cases are accompanied by explosions.
The action of an air shock wave on a building is characterized by a complex set of loads: excess pressure, reflection pressure, velocity pressure, leakage pressure, load from seismic waves.
Ensuring the preservation and restoration of buildings and structures includes measures to assess the possible degree of destruction of buildings and structures. Therefore, in modern conditions, the design of buildings, structures and their elements is not possible without taking into account the dynamic effects. When designing and constructing buildings and structures, it is always necessary to take into account the resistance of structural elements to the action of damaging factors, both the explosion in general and the shock wave of the explosion in particular, which will help avoid future possible human losses.
Therefore, the article considers the general characteristics of the processes of interaction of the air shock wave with the building, the method of calculating the time of destruction of prefabricated buildings and the main parameters of the air shock wave which flows as a result of an explosion in a building, structure with windows, doorways and openings, which arose as a result of the destruction of floor structures or walls.
Studies have shown that the load on the structure depends on the parameters of the wave that flows through the holes in the buildings and through the holes formed by the destruction of the walls of the building, the comparison of calculated and experimental data indicates their sufficient convergence.

Purpose of research. Inspection and assessment of the technical condition of the enclosing structures of a residential building located at st. Engelsa, 107 in Kursk were carried out in connection with the development of the reinforcement project.Methods. Inspection of the technical condition of buildings and structures is necessary to determine the residual resource and service life of the building structures. The current regulatory documents require an examination of the technical condition of buildings and structures no later than two years after their commissioning. In the future, the inspection of the technical condition of buildings and structures is carried out at least once every 10 years and at least once every five years for buildings and structures or their individual elements operating in adverse conditions (aggressive environments, vibrations, high humidity, seismicity of the area 7 points and more, etc.). A permanent monitoring regime is established for unique buildings and structures.Results. In the process of examining a residential building located at st. Engelsa, 107, the following tasks have been solved: determination of damage to enclosing structures; analysis of the results of the study of the degree of wear of building structures; implementation of proposals for strengthening the brickwork. To eliminate the above damages, a proposal was developed to increase the rigidity of the above-foundation part of the building, having previously excluded soaking the foundation soil: by repairing the blind area and heating, water supply and sewerage networks.Conclusion. The solution of a narrow task of strengthening individual structures of buildings and structures may not give the desired result, therefore, when performing inspection work, it is necessary to consider the existing defects and damage in the complex. Within the framework of this work, we consider the strengthening of the load-bearing walls of a residential building with an increase in the overall rigidity of the above-foundation part of the building and the elimination of individual damages.

Abstract: In today's world, new concepts for skyscraper construction are required to mitigate the negative effects of seismic and wind forces. Since the world's most populous cities are experiencing land shortage, in this area tall buildings act as very important roles in modern cities. Due to the speedy increase in population and reduction in accessibility of land, vertical accommodation is obtaining a lot of preference which is resulting in vertical town development. Nowadays tall buildings rise higher and higher, with more and more complex and individual plan and elevation, such as multi-tower buildings. The multi-tower buildings refer to two or more towers connected with one large podium or conjunction parts at different levels. It is well known that the podium and conjunction parts shall be designed very carefully to meet the internal force and thedeformation between towers. Nowadays, when building multistory building, height is not the only pursuit. More unique forms are in trend to show the rich connotation and vitality of buildings. Connected twin tower structures conform to these requirements, and many connected structures in different forms have been or are being built in recent years. In present research work considering effects of influencing parameters like the height of the tower, connection with podium and depth of podium with two parallel towers (Twin-Tower). The main objective of this study is to analyze twin tower structure G+4 podium+25 floor building using linear dynamic earthquake analysis. We have considered four models with different combinations of twin tower with podium to achieve desirable results in terms of story drift, displacement and base shear under seismic forces for seismic zone IV and medium type of soil using Response Spectrum Analysis with the help of ETABS v19 software.

The understanding of the behavior of buildings during seismic events is paramount, particularly in regions susceptible to intense earthquakes. Through seismic analysis facilitated by tools like ETABS, engineers can craft structures capable of withstanding seismic forces. ETABS stands out as a versatile solution, accommodating a spectrum of structures ranging from elementary to intricate skyscrapers, whether static or dynamic. Its widespread adoption stems from its ability to cater to diverse building typologies. The engineers leverage ETABS to evaluate the structural integrity of buildings situated in earthquake-prone zones. This entails computing parameters such as sway, displacement patterns, and the magnitude of force the building's foundation must withstand. These analyses are instrumental in guaranteeing the structural resilience of buildings against seismic and wind-induced stresses.

Wooden structures are a substitute for such concepts as environmental friendliness and naturalness, therefore reinforced concrete structures are currently the main building material for the construction of multi-story buildings in Russia. The idea of building wooden multi-storey buildings is becoming more and more relevant every year. The emergence of new technologies and materials make this area of construction promising. Possible variants of structural systems using wooden elements are considered, based on the existing experience of using wooden structures as load-bearing elements of structures. The existing office building in St. Petersburg is taken as a basis. It is built using reinforced concrete structures. Calculations show, the proposed variants of building models using wooden structures are not inferior in physical, mechanical, and load-bearing indicators to a similar building made of reinforced concrete structures, moreover they surpasses in some cases. The experimental part of the work is aimed at the complete replacement of reinforced concrete structures with wooden ones. The results could make the construction of such structures profitable, but at the same time reducing the time for construction. Confirmation of this fact can be observed on successfully implemented multi-story buildings in European countries.

The paper presents the authors’ observations on the performance of buildings during the 8th October 2005, Kashmir earthquake in parts of Pakistan-administered Kashmir, and the North Western Frontier Province of Pakistan. A majority of the buildings in the earthquake region were non-engineered, owner-built, loadbearing masonry or reinforced concrete framed structures. Most of the masonry buildings were built with random or semi-dressed stone-walls without any reinforcement. The reinforced concrete frame buildings were deficient in strength, lacked ductile detailing and were poorly constructed. A large number of such buildings collapsed, leading to widespread destruction and loss of life. The building damage was the main cause behind the human and property loss. The collapse of floor and roof structures, the brittle behaviour of concrete buildings, a lack of integrity in masonry structures, and a lack of incorporation of seismically resistant features in building structures are found to be main reasons for the catastrophe.

Buildings are the most important objects in urban areas. Thus, building detection using photogrammetry and remote sensing data as well as 3D model of buildings are very useful for many applications such as mobile navigation, tourism, and disaster management. In this paper, an approach has been proposed for detecting buildings by LiDAR data and aerial images, as well as reconstructing 3D model of buildings. In this regard, firstly, building detection carried out by utilizing a Supper Vector Machine (SVM) as a supervise method. The supervise methods need training data that could be collected from some features. Hence, LiDAR data and aerial images were utilized to produce some features. The features were selected by considering their abilities for separating buildings from other objects. The evaluation results of building detection showed high accuracy and precision of the utilized approach. The detected buildings were labeled in order to reconstruct buildings, individually. Then the planes of each building were separated and adjacent planes were recognized to reduce the calculation volume and to increase the accuracy. Subsequently, the bottom planes of each building were detected in order to compute the corners of hipped roofs using intersection of three adjacent planes. Also, the corners of gabled roofs were computed by both calculating the intersection line of the adjacent planes and finding the intersection between the planes intersection line and their detected parcel. Finally, the coordinates of some nodes in building floor were computed and 3D model reconstruction was carried out. In order to evaluate the proposed method, 3D model of some buildings with different complexity level were generated. The evaluation results showed that the proposed method has reached credible performance.

The article is devoted to monitoring the technical condition of buildings and structures in operational conditions. Monitoring the technical condition of buildings and structures helps to understand the real condition and get recommendations for eliminating defects. Assessment of the technical condition of buildings and structures is necessary to ensure their operational suitability. Usually, monitoring includes a number of different methods that allow to assess the technical condition of the object in dynamics based on periodic (monthly, weekly) observations. The relevance of research was emphasized, which was determined by the practical need to assess the technical condition of the load-bearing structures of buildings and structures under the influence of natural and climatic factors and human activity, which would allow predicting the occurrence and development of emergency situations with high reliability. The purpose of the work is established, which consists in the development of a theoretical-experimental methodology for assessing the technical condition of load-bearing structures of buildings and structures during monitoring using modern information technologies for data acquisition and processing. An analysis of modern natural (experimental) methods of assessing the technical condition of buildings and structures, as well as computer modeling methods, was carried out. The expediency of conducting the survey, which consists in establishing the real bearing capacity and operational suitability of the building (structure), is indicated. The purpose of the survey is to obtain data to determine the reliability of the building, the need for strengthening, repair, reconstruction, modernization and development of the necessary project documentation. The principles of building a system for monitoring the technical condition of buildings (buildings), the basic structure, and engineering solutions were described. An analysis of the main theoretical methods of modeling the technical condition of the building was carried out. The method of building an information system for obtaining data from sensors of physical parameters, as well as recording, processing, comparing with theoretical models and making management decisions in case of deviation of operational parameters from permissible values was given. It is proposed to solve the inverse problem using predictive mathematical models, namely: designing a building (structure) with predetermined (according to the project) parameters of technical condition and operational reliability.
