Earthquake causes considerable damage to a large number of RCC high-rise buildings and tremendous loss of life. Therefore, designers and structural engineers should ensure to offer adequate earthquake resistant provisions with regard to planning, design, and detailing in high-rise buildings to withstand the effect of an earthquake and minimize disaster. As an earthquake resistant system, the use of coupled shear walls is one of the potential options in comparison with moment resistant frame (MRF) and shear wall frame combination systems in RCC high-rise buildings. Furthermore, it is reasonably well established that it is uneconomical to design a structure considering its linear behavior during earthquake. Hence, an alternative design philosophy needs to be evolved in the Indian context to consider the postyield behavior wherein the damage state is evaluated through deformation considerations. In the present context, therefore, performance-based seismic design (PBSD) has been considered to offer significantly improved solutions as compared to the conventional design based on linear response spectrum analysis.

Abstract: Architects nowadays develop attractive edifices, and floating columns are widely employed in this process. Floating columns are used not only to provide a magnificent perspective but also when a vast open area is necessary. Edifices with irregular configurations are more vulnerable to earthquakes and hence, suitable shear wall placement is required to ensure the edifice's stability. Many multi-storey edifices collapsed in seconds after the Bhuj Earthquake (Jan 26, 2001), due to the presence of soft stories, floating columns, and mass anomalies. As a result, knowing the seismic reactions of these buildings are vital for constructing earthquake-resistant assemblies. The relevance of a Floating Column and the existence of a shear wall in an irregular multistorey building is highlighted in this study. Dynamic seismic behaviour of a G+18 irregular edifice with different locations of the floating column and different positions of the shear wall is explored in this research. The edifice is analysed and compared with the model without shear walls and floating columns to examine the alterations. The dynamic analysis is carried out using Response Spectrum Analysis and storey drift, storey displacement and base shear are calculated and finally, software compression is computed for different zones. The analysis is carried out by Indian standardized codes IS 1893:2016 and IS 456:2000 which are the codes specified by the Bureau of Indian Standards for earthquake resistance edifice design and plain and reinforcement concrete design respectively. Keywords: Floating Column, Shear Wall, Irregular Edifice, Seismic behaviour, Response Spectrum Analysis, storey drift, storey displacement, base shear.

Abstract A hybrid structure is one that combines more than two different types of materials to compensate for weak places while also maximizing strength. Hybrid steel and concrete frameworks, as well as other modern materials, are unified at the member or framework unit. Hybrid structures are frequent in high-rise and super-high-rise building projects, and they provide the benefit of cost savings. Shear walls are built to withstand lateral loadings like earthquakes and winds loads. The response spectrum analysis approach is frequently used to measure design stresses for earthquake-prone structures. The modelling and analysis of the regular plan structures are done by CSI ETABS 2019 in IV seismic zones, on type II (medium soil) of India According to IS 1893 (Part-1) 2016. The aims of this study Response spectrum analysis of 41 storey RCC and hybrid structures with shear walls and without shear walls are compared. RCC and hybrid structures with shear walls showed lower storey displacement, storey drift, and story shear values than RCC and hybrid structures without shear walls, according to the results of this study. The research results will be helpful as a reference and a tool for seismic analysis of hybrid structures.

Dynamic Nonlinear Analysis

The most common analysis methods of complex high-rise buildings are the response spectrum analysis, elastic time history analysis, pushover analysis and etc. Meanwhile, for the analysis of those high-rises whose height is higher than 200 meters, period is longer than 4 seconds, the dynamic nonlinear analysis would be more accurate. In this paper, the dynamic nonlinear analysis was executed in use of the Perform-3D program. The results show that the maximum top displacement can meet the national codes; most tie beams and the frame beams of the upper structure yielded in the IO~IS stage and parts reached the CP stage; both the laminated columns and the frame columns had a good performance on the shear behavior; and it is also proposed to strengthen the reinforcement at the reducted storeys. By all these above, it can be judged that the structure reached the codes’ seismic performance objectives.

Nowadays, the number of buildings is constructed and designed according to the requirements and aesthetic viewpoints of the buildings every day. Most buildings are constructed in a certain spatial configuration, such as X-shaped, V-shaped, and the x and y coordinates are not parallel to the structure. The earthquake caused more damage to the different structures of the building. The main problem is the slenderness ratio. The main purpose of this project is to compare the dynamic characteristics of buildings with different structural configurations in seismic zones and soil types. In this study, a 12-story space configuration structure was considered, and the height of 3m on each floor did not exceed 36m, with shear walls and supports at different positions of the building. The dynamic behaviour of buildings in all seismic zones of magnitude III and on different types of soil (such as media) is studied. The structure has peripheral beams that carry RC shear walls with a thickness of 230 mm. The response spectrum analysis was carried out by using software of ETABS version

Nowadays highly increases in the high rise building with architectural requirement in modern city. The purpose of the study is to understand the response of the building due to vertical irregularities. 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: There are several natural calamities, including flooding. worst natural disaster – quake, drought, tornado, hurricanes, and earthquake are the most devastating. Since it leaves a trail of injuries and financial losses fear-inducing behaviors. Implementation is necessary When it comes to earthquake codes in building design, earthquakes are like a wake a wake-up call is made. Urban areas in India are seeing a growth in the popularity of medium-rise as well as high rise R.C.-framed apartment complexes with storey counts ranging from 8 to 10 and even greater than 20. R.C. framed buildings of these heights are equipped with shear walls to resist lateral loads. Thus, it's important to understand how they affect storey drift and stiffness, as well as shear and moments, as well as stress within the shear walls. In order to determine the strength of the building's shear wall, a three-dimensional analysis is performed by Response spectrum. In this study we will be using a shear wall on one structure and friction dampers on another, we will create and analyses a 30-story high-rise structure and compare the results based on the parameters listed above, by using E-tabs software.
