Coupled Structural-thermal Calculations for Restrained Steel Columns in Fire

Abstract

This work presents a coupled structural-thermal numerical analysis of restrained steel columns under elevated temperatures. The modeling is based on the experimental tests carried out on a series of open section ‘I-shaped’ columns, tested experimentally under different loading. The parametric study of a chosen case investigated following problems: geometrical imperfections, reduction of heated column area, variation of temperature along the length of the column, variation of applied force and variation of constraints properties. For the comparison with experimental the following quantities were used: axial force, vertical displacement and midspan deflection. The comparison showed that including more details and uncerteinties give the numerical results closer to reality. The last paragraph presents results for the same steel column under different loading, comparing only the maximum applied load, which is a crucial quantity for the behavior of the structure.
