［摘要］青島華潤中心悅府項目一期工程包括2棟超高層和3棟高層建筑，采用混凝土剪力墻結(jié)構(gòu)體系。2棟超高層建筑結(jié)構(gòu)高度201.15m，由于底部大堂空間需要，有4片剪力墻在3層樓面轉(zhuǎn)換；3棟高層建筑結(jié)構(gòu)高度105-75m。采用SATWE和ETABS軟件進行了小震彈性計算，并比較了安評報告與規(guī)范中規(guī)定的不同地震動參數(shù)取值所對應(yīng)的結(jié)果，結(jié)果表明，結(jié)構(gòu)的周期比、層間位移角等均滿足規(guī)范要求。采用MIDAS/Gen對結(jié)構(gòu)進行動力彈塑性分析，結(jié)果表明，結(jié)構(gòu)抗震性能較好，可滿足預(yù)設(shè)的罕遇地震作用下的抗震性能目標(biāo)。

Abstract:The first phase project of Qingdao Huarun Center Yuet House includes two super high-rise buildings and three tall buildings. Concrete shear wall structural system is adopted. Structural height of 2 super high-rise buildings is 201m. Due to the need for the bottom lobby space, there is a floor transfer of 4 pieces of shear walls on third floor. Structural height of 3 high-rise buildings is 105-75m. Programs of SATWE and ETABS were used to conduct elastic calculation under the frequent earthquakes, and results corresponding to different dynamic parameter values of safety evaluation report and codes were compared. Results show that period ratio and interlayer displacement angle of the structure meet specification requirements. MIDAS/Gen software was used to conduct dynamic elastic-plastic analysis on the structure. The results show that the seismic performance of the structure is well, which can meet the preset seismic performance objectives under rare earthquake.
Keywords:super high-rise building； multi-tower； height-wide-ratio； dynamic elastic time-history analysis； dynamic elastic-plastic analysis
