Abstract

The steel structures are widely used in modern industrial factory due to its advantages such as high strength, good plasticity, good sealing property, and short construction period. However the poor fire-resistance ability is the most significant weakness of the steel structures. The steel structure workshop is very easy to collapse and damage as long as the fire occurs. So it is very meaningful to study the collapse of steel structures under fire conditions. In this paper, one storey industrial factory buildings with light steel is used as an example and the influence of the intermediate support on the collapse of the steel structure is analyzed by using the finite element software ansys15.0. The damages of the structures are analyzed under the same temperature and load size of the structure. The results show that when the intermediate support is added in the workshop, it can ef-fectively prevent the rapid collapse of the structure and delay the failure time of the structure. Therefore, in-creasing the intermediate support can effectively improve the overall stability of the structure and we should increase the intermediate support to the workshop in engineering practice.
