[摘要]長沙華遠(yuǎn)·金外灘三四期綜合體項目中的T1塔樓結(jié)構(gòu)高度為262.99m,屬超B級高度超限高層結(jié)構(gòu),采用鋼筋混凝土框架-核心筒結(jié)構(gòu)體系。小震下的反應(yīng)譜分析結(jié)果表明結(jié)構(gòu)的周期比、剪重比、層間位移角等均滿足規(guī)范要求。在反應(yīng)譜分析的基礎(chǔ)上,利用ETABS軟件對結(jié)構(gòu)進(jìn)行了彈性時程反應(yīng)分析,結(jié)果顯示,時程分析結(jié)果的平均值基本都小于反應(yīng)譜分析的結(jié)果。在小震分析的基礎(chǔ)上,選取了幾個關(guān)鍵結(jié)構(gòu)構(gòu)件進(jìn)行了中震不屈服校核,結(jié)果顯示,構(gòu)件能夠滿足中震不屈服的性能目標(biāo)。

Abstract: The structural height of T1 tower of the 3rd and 4th phase buildings of Huayuan Golden Bund in Changsha is 262.99 meters. It is an out-of-code high-rise building which exceeds the B level requirements of the code and the structural system of reinforced concrete frame core-wall is adopted. Response spectrum analysis results under the frequent earthquake show that the parameters of period-ratio, shear-weight ratio and interlayer displacement angle can satisfy the requirements of the codes. Based on the response spectrum analysis, elastic time-history analysis was conducted by using ETABS software. The analysis results show that the average results of time-history analysis are smaller than that of response spectrum analysis in general. On the basis of response spectrum analysis under the frequent earthquake, non-yielding analysis under the moderate earthquake was checked in some selected key structural members and the results show that the selected members can meet the requirements of the performance objective of nonyielding under the moderate earthquake.
Keywords: frequent earthquake; response spectrum analysis; time-history analysis; moderate earthquake
