[摘要]介紹了天津現(xiàn)代城酒店塔樓及裙房多重復(fù)雜情況以及裙房體型收進(jìn)、第一道加強(qiáng)層以上的豎向收進(jìn),并針對這兩種類型的收進(jìn)提出了增強(qiáng)抗震性能的措施。結(jié)果表明,裙房逐步收進(jìn)可以有效減小結(jié)構(gòu)豎向剛度突變;在第一道加強(qiáng)層上下的混凝土剪力墻內(nèi)設(shè)置鋼板可以減小剛度突變引起的損傷。另外詳述了鋼板-混凝土組合剪力墻的設(shè)計(jì)要點(diǎn)及構(gòu)造。

Abstract: The multiple complicated conditions of the tower building and the podiums of Tianjin Modern Hotel were introduced as well as the vertical setback of the podiums and the vertical setback above the first strengthening story. Measures were proposed in corresponding to the two kinds of setbacks to improve the seismic performance. The results show that gradual setback of the podiums is effective to reduce the vertical stiffness mutations. Setting steel plate in the concrete shear wall near the vertical setback above the first strengthening story is feasible to reduce the damage due to the stiffness mutations. The design approach and details of steel plate-concrete composite shear wall were introduced in detail.

Keywords: multiple complexity; super high-rise structure; setback; steel plate-concrete composite shear wall
