［摘要］長沙華遠·金外灘三四期的R1&R2塔樓為超限高層建筑，高寬比為10.8。對結(jié)構(gòu)進行了小震下的反應(yīng)譜分析，并分別運用SATWE和ETABS兩種軟件進行整體計算、分析和對比。在反應(yīng)譜分析的基礎(chǔ)上，利用ETABS軟件進行了彈性時程反應(yīng)分析，分析結(jié)果滿足現(xiàn)行規(guī)范的相關(guān)要求。根據(jù)工程自身的特性，對結(jié)構(gòu)設(shè)定了適宜的性能目標，完成了在設(shè)防烈度地震下中震彈性和中震不屈服的計算分析；采用ABAQUS軟件對結(jié)構(gòu)進行大震下的動力彈塑性時程分析，實現(xiàn)結(jié)構(gòu)的性能化設(shè)計。工程對風荷載較敏感，舒適度計算是結(jié)構(gòu)設(shè)計的主要控制指標之一。

Abstract: The R1&R2 tower building of the 3rd and the 4th phase buildings of Huayuan Golden Bund in Changsha is an out-of-code high-rise building. The height to width ratio of the building is 10.8. Response spectrum analysis of the structure under the frequent earthquake was done.SATWE and ETABS software were used to carry out integral calculation, analysis and comparison of the structure. Based on the response spectrum analysis, elastic time-history analysis was conducted by ETABS software and the results can meet related requirements of the present code. According to the characteristics of the project itself, the appropriate seismic performance objectives of the structure were set, the elastic and non-yielding analysis under the medium earthquake were completed. Dynamic elastic-plastic time-history analysis was conducted by ABAQUS software under the rare earthquake to ensure the completion of performance-based design. This project is sensitive to wind load, so the human comfortableness is one of the main control factors in design.
Keywords: height to width ratio; response spectrum analysis; time-history analysis; performance-based design; human comfortableness
