Abstract

Abstract: This paper presents modelling of the progressive failure of steel moment frames subjected to localised fire. A finite element approach using the software ABAQUS has been developed to analyse the structure. An explicit-dynamic solution was adopted to solve the non-convergence problems caused by element buckling. A series of validation analyses were carried out to ensure that the results were within an acceptable level of accuracy. The analysis results are shown to match well with the previous experimental data and analysis. This modelling approach allows detailed insights to be obtained into the structural robustness of such frames in fire situations.
