ABSTRACT
This paper utilises a 3D numerical model to simulate behaviour of composite steel frames in fire following earthquake. The aim of this study is to provide insight into the effect of prior earthquake damage on structural behaviour in fire. It compares structural behaviour of the frame in two different conditions, Fire in normal conditions (F) and Post-Earthquake Fire (PEF). The earthquake analysis is performed using pushover analysis and then is followed by fire analysis using the Eurocode parametric fire. Additionally the effect of fire insulation delamination during earthquake is also taken into account. The contrast in behaviour of the two conditions is presented and explained.
