The Mechanical Performance Analysis of Steel Truss in the Fire and Damage Assessment after Fire

Abstract:

At present, based on the fire test results of single components, the design method of structure fire resistance performance is put forward. However, the cases for fire resistance research of space structure are not widely researched by scholars. Making use of finite element software to analyze structural fire resistance performance will be development trend of the research topic. In the paper, the author regards the truss structure in practical engineering as the research object. And by using thermal software (FDS), the environment temperature in every space position can be calculated to get steel’s fire temperature further. In the hot-force coupling module, structural mechanical behavior is analyzed after fire, and structural damaged degree is judged on the basis of the building identification level standard, which will be helpful to provide the repair opinion.
