Research on the Mechanical Properties of the Castellated Lightweight Steel Portal Frame
Based on the ANSYS, castellated lightweight steel portal frames are modeled to analysis the stress destruction process and stress distribution rule under horizontal and vertical loads. The comparative analysis with the original solid-webbed portal frame in yield load, ultimate load, the mid-span deflection is pursued. The results show that: there are some differences in failure mode between the castellated lightweight steel portal frame after expansion and the original solid-webbed portal frame. The former bearing capacity and rigidity increase by a large scale than the latter.
