Abstract

In order to analyze the damage mechanism and response of the high steel structure during a fire

the mathematical fire response model based on ABAQUS was presented.The fire response of high steel structure with different stories and different fire positions was simulated and analyzed.The deformation and failure process of steel structure in local fire was simulated.By analyzing the damage mechanism of the high steel structure under the combined action of fire and loads

the influence range and factors of local fire to the steel structure were investigated.Then

the failure modes of the steel structure with varied building heights and loads were given and the reason that caused these failure modes was analyzed.
