Stability Analysis of an RC Structure with RC Shear Walls in the Event of a Fire

EasyChair Preprint 3092

Abstract

Reinforced concrete (RC) shear walls are considered as one of the main lateral load resisting structural members in RC buildings. Apart from acting as a lateral load resisting system, the RC shear walls tend to provide ductility, stability and stiffness to the structure. In the present work,  an analysis is carried out to assess the residual response of a fire exposed reinforced concrete structure, by considering the presence of RC shear walls contributing towards the stability of such a structure exposed to fire. The analysis carried out in the present work includes the study of the stability of a multi-storeyed RC building with and without shear walls exposed to high temperatures developed due to fire by considering the degraded values of the material properties with respect to the exposure temperatures. The results from this study indicates that, inclusion of  shear walls in different locations in the building has a predominant effect on the stability of the RC building in the event of a fire.

Keyphrases: degenerated material properties, fire exposure, high temperature, shear walls, structural stability
