Fire resistance analysis of steel structures

Abstract

Experimental studies conducted to test simple computation models for the determination of resistance of steel structures exposed to fire, as defined in HRN EN 1993-1-2:2008, are presented in the paper. The analysis is made for basic parameters defining reduction of mechanical properties of steel at elevated temperatures, and for basic models for calculating fire resistance of elements subjected to cross-sectional load, and transverse and longitudinal load (bending and bending with longitudinal force).
