It is emphasized on seismic design of H-type No.4 dwelling house building in Qiangsheng Gubei Garden in Shanghai, which is evident in torsion effect on seismic action.The program SATWE and PMSAP are used to analyze seismlc action in both cross and side sections, and make adjustment in structure distribution accordingly in order to ensure requirements of seismic fortification criterion and every seismic calculative index of seismic code basically.
Keywords: eccentric structure; aseismic design; mass center; rigidity center; torsion effect
