[提要]  針對(duì)強(qiáng)生古北花園中4號(hào)樓H型住宅樓結(jié)構(gòu)抗震設(shè)計(jì)中存在的明顯扭轉(zhuǎn)效應(yīng)問題，采用SATWE和PMSAP兩種程序進(jìn)行了正交和斜交兩個(gè)方向的抗側(cè)力計(jì)算分析，并且對(duì)結(jié)構(gòu)布置作了針對(duì)性調(diào)整，使結(jié)構(gòu)的各項(xiàng)計(jì)算結(jié)果基本符合建筑抗震設(shè)計(jì)規(guī)范的規(guī)定，達(dá)到抗震設(shè)防的要求。
[關(guān)鍵詞]  偏心結(jié)構(gòu)  抗震設(shè)計(jì)  質(zhì)量中心  剛度中心  扭轉(zhuǎn)效應(yīng)

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
