In order to protect Chinese ancient buildings, Shen-Wu Gate in the Forbidden City is taken as an example to study its aseismic character under 8-degree of seldomly occurred earthquake by pushover analysis. Based on constitution of tenon-mortise joint and tou-kung, finite model of the structure is built. By modal analysis main mode of the structure is obtained, based on which level loads is applied to the structure to carry out pushover analysis. Results show that mode 1 in y direction is main mode of the structure. Under 8-degree of seldomly occurred earthquake the structure produces displacement which is less than permissible value. Under earthquake plastic hinges mainly appear near bottom tenon-mortise joints. However the upper part remains intact because of isolation of tou-kung.
