［摘要］銀川德豐大廈建筑高度210m，屬超B級(jí)高度高層建筑，采用鋼管混凝土疊合柱框架-核心筒結(jié)構(gòu)體系。針對(duì)項(xiàng)目特點(diǎn)和超限情況，確定了合理的結(jié)構(gòu)抗震性能目標(biāo)，選擇了合理的地震動(dòng)參數(shù)，進(jìn)行了小震、中震、大震下的各項(xiàng)計(jì)算分析，特別是中震不屈服下核心筒墻肢拉應(yīng)力計(jì)算和中震、大震彈塑性變形計(jì)算。采取消能減震措施，用防屈曲耗能支撐（BRB）作為桁架斜腹桿參與耗能，起到“保險(xiǎn)絲”的作用；針對(duì)各階段分析結(jié)果，提出了有針對(duì)性的抗震加強(qiáng)措施，可為8度區(qū)同類超限高層結(jié)構(gòu)設(shè)計(jì)提供參考。

Abstract:Defeng Building in Yinchuan is a 210m high super-tall building that exceeds height requirement of B category high-rise building, and it adopts steel tube concrete composite column frame-corewall structural system. Considering project characteristics and out-of-code conditions, the reasonable seismic performance objectives were determined and reasonable seismic motion parameters were selected. And various calculations and analyses under frequent, fortification and rare earthquakes were carried out. Particularly, the tensile stress of wall\|column of corewall was calculated under performance goal of non-yielding under fortification earthquake, and the elastic-plastic deformation calculations under fortification and rare earthquakes were carried out. Energy dissipation measures were taken and the buckling restrained braces were used as truss diagonal web member to contribute to energy dissipation, which act as a fuse. Specific strengthening measures were proposed according to the analyses results of different stages. The study can provide reference to the structural design of similar out-of-code high-rise buildings in the regions with seismic fortification intensity of 8 degree.

Keywords:super-tall building; seismic design; strengthened story; local component transfer
