Steel structure has been widely used in the design and construction of large venues because of its high strength, light weight and good seismic performance. However, because of the need to consider its seismic performance and instability, how to better design and construction of steel structures is particularly important. This paper starts from three aspects: steel structure stability design method, steel structure optimization design method and steel structure earthquake resistance method. The balance method, energy method and dynamic method of stability design are summarized. The case of folded string steel truss structure is summarized and analyzed, and the feasibility of the steel structure stability design method combining shape optimization and topology optimization is obtained. In addition, for the steel structure seismic, pushover analysis method and the incremental dynamic analysis (IDA) method are used. Finally, this paper summarizes the shortcomings of stability design, optimization design and seismic design in the field of steel structure design.
