Numerical assessment of a steel bridge subjected to Wildland Urban Interface (WUI) fires
The focus of this research is to assess the performance of a steel plate girder bridge subjected to WUI fire events. Fire scenarios were modelled with physics based Fire Dynamic Simulation(FDS). Sequentially coupled heat transfer analysis gave the temperature distribution of the bridge. 12mm Web area experienced the highest temperature development of 350C . This leads to a 25% of decrease of steel Youngs modulus.
