  • Abstract:
  • Many buildings in the present situation have irregular configurations both in plan and elevation due to aesthetic consideration and city regulation, which in future may be subjected to devastating earthquakes. Irregularities are not avoidable in construction of buildings. However, the behavior of structures with these irregularities during earthquake needs to be studied. Structural irregularities have a significant effect on reinforced concrete buildings during an earthquake. In order to prevent a collapse mechanism caused because of structural irregularities, seismic demand must be determined accurately. The present work aims to investigate the seismic evaluation of multi-storied RCC irregular buildings (L, T, Y, C & E) shapes with combination of irregularities as mass, stiffness and geometric considering concrete bracing, Steel bracing, BRB bracing and SMAs bracing. The performance of a 20-story RCC moment resisting frame is evaluated following seismic code IS-1893:2016. The Non-Linear Time History Analysis of models being considered in the study, the ground motion data of the most severe earthquake in India, the Bhuj earthquake 2001, is used. In Non-Linear Time History Analysis, Fast Non-Linear Analysis (FNA) is used with the help of the ETABS 2021.
