Abstract

For analysis of a column the finite element method can be used. The behaviour of a steel column which is exposed to fire is examined. This paper uses the calculable method of a truss model, because it is known that a simple truss model produces similar results to finite elements models. A short computer program is used for the step-by-step nonlinear structural analysis of steel column subjected to fire using truss model. The column is simulated by a truss model (Fortran). The simulation of steel structural element (column) by truss is suggested, because the truss model has a very simple stiffness matrix in comparison to other usual finite elements and can in a simple way describe the nonlinear of the stress-strain law of material in addition to the geometrical nonlinearity. The aim of the present work is to investigate the behavior of steel column exposed to fire.
