Problems solved by technology

[0003] Most of the existing prefabricated light steel houses adopt steel frame structure, slab-column structure, wall panel structure and cold-formed thin-walled steel structure system. , it faces defects such as insufficient lateral force resistance and poor seismic performance.
Flange connection is a connection form of square steel pipe columns or round steel pipe columns connected by bolts. It has the advantage of replacing on-site welding and improving the efficiency of connection construction. However, the stiffness of flange joints is low and it is easy to slip when stressed. It is only regarded as a hinge joint, and it is difficult to meet the requirements of rigid connection between columns
