Seismic Response Study of RCC Structures

Abstract

The subject entails analysing how rcc structures respond to earthquakes.

Sylhet, which is situated in one of South Asia's most seismically vulnerable regions, is the most seismically vulnerable city in Bangladesh. It is strongly advised to do a seismic performance analysis before designing safe and dependable construction systems for this site. Structural engineers must assess the system configuration both statically and dynamically to maximise the performance of the reinforced concrete (RCC) shape. In compliance with Bangladesh National Building Code (BNBC)-2006, the goal of this study is to perform static and dynamic evaluation on a single, conventional and strangely shaped RCC building frame while accounting for the same span for each body. Using ETABS v9.7.1 and SAP 2000 v14.0.0, this study examines four different ten-story RCC building frames (W-form, L-shape, rectangle, and rectangular) for Bangladesh's seismic zone 3. (Sylhet). Comparisons between the maximum displacement caused by static loading and the dynamic reaction spectrum of variously built structures have been investigated. According to the impacts assessed, the effects of seismic pressure for static load analysis are essentially equal to all other models except model 1. (W-shape). It has been found that the W-shape is more susceptible to seismic load scenarios. The displacements for building frames with unusual shapes are larger than those for buildings with conventional shapes, according to the response spectrum study. Overall, traditional buildings perform better than unconventional ones.
