Behaviour of Composite Structure under Fire

Abstract

The purpose of this paper is to investigate the behaviour of composite structure under fire. The main objective of fire structural analysis is to predict the effect of fire on buildings. The resistance and the structural performance under heating caused by the fire depends on the material degradation at elevated temperature. Elevated temperature is a potential threat for any structural building that Can cause damage. Effect of temperature depends on the material properties, mechanical boundary conditions, loading, and thermal conditions. Response of composite material made up of concrete and steel exposed to fire is considered for the study. This paper focuses on the structural analysis of a composite structure under Fire loading. Six storeyed structure is considered for the analysis. SAP 2000 and Etabs software is used for modelling and analysis of composite structure With mechanical properties. Fire load is applied at different fire locations. The primary objective of this work is to check the effect of temperature variation on deflection of composite structure.
