江苏新长江(雅阁)国际酒店B塔楼结构高度为126.4m,属超高层结构。对结构进行了多遇地震下的反应谱分析,为了使分析结果安全可靠,分别运用PKPM和ETABS两种软件对结构进行分析,并将结果进行对比。结果表明,两种软件求得的结构各主要参数结果都基本一致,误差很小,从而证明了计算结果的正确性。在反应谱分析的基础上,利用ETABS软件对结构进行了弹性时程反应分析,时程分析时选取了2条天然波和1条人工波,分析结果显示,时程分析的结果基本都小于反应谱分析的结果。在多遇地震分析的基础上,选取了几个主要结构构件进行了中震不屈服校核,结果显示,构件能够满足中震不屈服的性能目标。
Jiangsu New Yangtze River (Accord) International Hotel B tower structure height of 126.4m, is a super high-rise structure. In order to make the analysis results safe and reliable, the structure of the structure was analyzed by spectrum analysis software PKPM and ETABS, and the results were compared. The results show that the results obtained by the two softwares are basically consistent with each other, the error is small, which proves the correctness of the calculation results. Based on the analysis of the response spectrum, ETABS software was used to analyze the structure of the structure by elastic time-history analysis. Two natural waves and one artificial wave were selected in the time history analysis. The analysis results showed that the results of the time-history analysis were basically less than the response Results of spectral analysis. Based on the analysis of many earthquakes, several major structural members were chosen to conduct the earthquake proofing without yielding. The results show that the members can meet the performance target of no yield under moderate earthquakes.
