文摘

The paper deals with the linear stability loss of metal bearing structures which are thermally loaded. The source of the thermal load is burning and it acts on the metal construction. Analysis of combustion and spread of fire can be simulated using computational program Fire Dynamics Simulator (FDS). An elastic and elastic-plastic temperature-dependent material model is considered in the structure. FEM ADINA software is used for the stability loss analysis of the structure. Mapping algorithm of burning simulation is used for the results transfer from the FDS into the ADINA program. The linear and nonlinear loss of stability calculation of the steel bearing structure is subsequently realized in the ADINA.
