Application of the hot rolled H-shaped steel in the large industrial workshops;

Using Finite Element Method program ANSYS as well as considering the initial imperfections such as initial geometrical imperfections,residual stresses and cold-formed effectiveness,the axial compressive ultimate loading capacities are analyzed of cold-formed steel square hollow section member、rectangular hollow section member with thick wall and hot-rolled H-section member.

The critical conditions on eliminating fire protection cover for steel portal frames;

Research on sloped beam of steel portal frame about temperature distributing under local fire

Using the finite element analysis software ANSYS,the critical temperatures of steel portal frames in fire affected with varied factors are investigated.
