Comparison Of Seismic Behaviour Of Typical Braced Multistorey RC Structure With Composite Structure

Abstract

This project investigates the seismic behavior of two distinct types of multistory reinforced concrete (RC) structures: a typical braced structure and a composed structure. Seismic forces present significant challenges in structural design, particularly in multi-storey buildings where how the lateral forces are distributed can lead to varying levels of stress and deformation. This study aims to compare these two structural system’s performances under seismic loading by analyzing parameters such as base shear, storey drift, and displacement. Using advanced structural analysis software, the dynamic responses behaviour of the structure reinforced of both systems are evaluated through time history and spectrum of responses analyses. The results provide insights into the relative advantages and limitations of bracing systems and composed structures in mitigating seismic impacts, ultimately guiding the design of safer and more efficient multistory buildings in seismic-prone regions.
