A nonlinear finite element analysis(FEA) model was proposed to simulate a semiconductor display industrial building equipped with a steel frame brace as a practical engineering case study. The seismic performance of the structure under frequent and rare earthquakes was analyzed. The results show that the overall indexes of the structure meet the requirements of the design codes. However, the inter-story displacement angles of the 3rd and the 6th floors are relatively large. Under rare earthquakes, damage to the members is mainly concentrated in the steel braces. Slight damage occurred in the corner columns at the bottom floor and side beams at middle floors of the structure. The steel braces are shown to effectively improve the structural stiffness and reduce damage to the beams and columns.
