This research is based on the gradient heating mode of ANSYS software APDL language to study the structure stress of the whole warehouse. This paper shows the finite element analysis result of portal steel frame structure with different connections in fire. There are two ways to analysis the connection between beam and column: rigid connection and pin joint. The overall deformation of pin joint is larger than that of rigid connection, while the equivalent stress suffered by the dangerous parts in rigid structure is larger than that of pin structure.
