Authors: Md. Abdul Basit1* , Ishtiaque Ahmed
Published: 2025-June-01

Finite element modelling is performed in this study for reinforced concrete columns which is subjected to thermal load (fire). Previous experimental studies observed the fire behavior of reinforced concrete columns but no studies observed the fire behavior of such columns having different cross sections and reinforcement ratios numerically. Fire is applied to the surface of the columns in the form of thermal load. Convection and Radiation has been applied accordingly to the column surfaces. Temperature dependent material properties has been given as input. In this research, numerical analysis is done in ABAQUS software and results are analyzed in terms of fire resistance, maximum temperature developed, temperature contour etc. The fire resistance found using the finite element model demonstrates excellent consistency with standard furnace test outcomes of former research verifying the dependability of the model
