Abstract:The space relation of China National Film Museum is very sophisticated. Structure type selecting and aseismic system are the emphasis of structure design. By means of pushover analysis, the structural performance under rare earthquake is studied. Through construction analysis of the truss with 70m\|span, the construction technique of up\|bearing method is presented, which proved to be efficient.
Keywords:space teal structure; pushover analysis; construction analysis; up\|bearing construction technique
