Seismic Control of RCC Frame Using Linear Bracing System

Abstract

This paper presents the seismic behavior of different bracing system in G+9 storey RCC frame with steel bracing. A linear analysis is carried out to on different braced G+9 storey RCC frame to capture the seismic response. In this study Concentric & Eccentric bracing system were used with their different types. The primary goal of this study is to investigate the seismic behavior of different bracing system under seismic load. It is seen that the type of bracing system significantly influence the performance of high rise RCC frame. The seismic performance of G+9 storey RCC frame with steel bracing is measured in terms of displacement, moment. It can be concluded from the study that bracing system increases the stability of structure, moment resisting capacity of the structure. In concentrically braced frame inverted V bracing & in eccentrically braced frame knee X bracing is more suitable than any other bracing system. Eccentrically braced frame reduced more moment than concentrically braced frame.
