This paper attempts to reduce the seismic hazards of building structure with an intelligent material called piezoelectric ceramics (PC). Specifically, the author designed a self-reset piezoelectric friction damper (SRPFD) based on laminated PC, and the number and position of dampers were optimized with genetic algorithm (GA) on the Matlab. On this basis, a large 24m×24m square pyramid space truss structure model was created, and the GA was optimized by the Gads toolbox. Then, 60 SRPFDs were selected to analyze the seismic response of the building structure. The results show that the control effect of the SRPFDs was improved by nearly 32.5% after the optimization. This research findings shed new light on semi-active optimization control of space grid models
