Experimental and Numerical Analysis of Steel Frame Structure Exposed to High Temperature

Abstract

Structures exposed to fire loading, where supports prevent thermal expansions, must be calculated according to the basic principles of mechanics while respecting the effect of rising temperature on the structure and its effect on the value of variable material properties at the time of fire. The paper analyzed and compared results of the experiment aimed to verify the behavior of statically indeterminate steel frame exposed to high temperature and numerical modelling using finite element method in the ANSYS software.
