Study of the effect of global and local ductility on high - rise RCC building in high seismic zone

Abstract

Numerous studies have been conducted on high-rise buildings, focusing on various aspects such as construction methods, building materials, and responses to seismic and wind pressures. In this paper, the influence of plan aspect ratio on the behavior of high-rise buildings is examined in detail. According to IS 16700:2017, the plan aspect ratio is limited to 5. However, in this study, the plan aspect ratio has been studied up to 6, and the behavior of high-rise buildings under seismic forces has been investigated. The building model has been constructed in three sets, each with varying heights. Building heights of 10, 20, and 30 stories have been selected for each group of buildings, respectively. For each set, seismic metrics, including ductility, stiffness, and base shear, have been compared, and conclusions have been drawn.
