［摘要］中國華融大廈項目中五星級酒店塔樓地上32層，建筑幕墻高度150m，結(jié)構(gòu)高度144m，由于地處臺風(fēng)登陸區(qū)，建筑平面狹長造成結(jié)構(gòu)高寬比較大，風(fēng)荷載屬于控制荷載，結(jié)構(gòu)體系采用抗側(cè)剛度較大的鋼筋混凝土框架-剪力墻結(jié)構(gòu)，加之同時存在扭轉(zhuǎn)不規(guī)則、多處局部轉(zhuǎn)換和抗側(cè)剛度突變，酒店塔樓屬于超B級高度復(fù)雜超限高層建筑。針對本工程的結(jié)構(gòu)特點，設(shè)計中采取多項抗震措施加以應(yīng)對，對主塔結(jié)構(gòu)進行小震彈性計算、風(fēng)振舒適度和抗傾覆驗算、靜力彈性時程分析、中震關(guān)鍵構(gòu)件承載力分析和罕遇地震動力彈塑性分析等。分析結(jié)果表明，采取的措施可行、有效，結(jié)構(gòu)各項指標(biāo)滿足規(guī)范要求，可達到預(yù)期的抗震性能目標(biāo)。

Abstract:The five-star hotel tower in China Huarong Mansion Project has 32 floors overground with structural height of 144m and it has 150m-high curtain wall. Located in the typhoon landing area where the wind load is the control load, the structural system adopts the reinforced concrete frame-shear wall structure with large lateral stiffness, because the structure has large aspect ratio due to relatively long and narrow plane shape. The hotel tower is a super B-class height complex out-of-code high-rise building, because it have a number of irregular indexes such as torsion irregularity, multiple local conversions and anti-lateral stiffness mutation. Aiming at the structural characteristics of the project, a number of seismic measures were adopted in the design to deal with the issues. The elastic calculation of the main tower structure under frequent earthquake, the wind vibration comfort and anti-overturning check, the static elastic time-history analysis, the bearing capacity analysis of the key components under fortification earthquake, and dynamic elasto-plastic analysis under rare earthquake were carried out. The analysis results show that the measures taken are feasible and effective, and the indexes of the structure meet the requirements of the specification and can achieve the expected seismic performance target.
Keywords:frame-shear wall structure; wind load; B-class height; local conversion; out-of-code
