Abstract
Cold-formed thin-walled steel buildings adopt the process of layered assembly, which is easy to disassemble and assemble and conforms to the requirements of industrial construction. But there is no clear method of seismic design. Taking a cold-formed thin-walled light steel structure house in Dazhou city as an example, the Pivot connection unit that can characterize the structural damage and the finite element software SAP2000 are used to establish a model, then this model is used to analyse the basic dynamic characteristics of structures and to analyze the time-history response of structures under seismic action. The results show that the simplified modeling analysis of the structure has a strong feasibility, and the lateral stiffness of the structure can resist the action of multiple earthquakes. Under the action of rare earthquake, the displacement between the layers of the structure is lower than the limit of the code, and the hysteretic performance of the structure is good, which can ensure the safety and reliability of the structure.
