［摘要］武漢誠功大廈主樓建筑平面呈切角三角形，主樓34層后框架角柱向內(nèi)收進(jìn)，形成斜柱，頂部設(shè)有鉆石造型。采用PKPM，ETABS軟件對(duì)結(jié)構(gòu)進(jìn)行彈性階段對(duì)比分析，并采用SAUSAGE軟件對(duì)結(jié)構(gòu)進(jìn)行大震彈塑性分析。依據(jù)主樓的超限情況，制定了基于整體及構(gòu)件的抗震性能化目標(biāo)，并針對(duì)結(jié)構(gòu)的不利部位、薄弱層、剪力傳遞樓層、斜柱及斜柱起始樓層采取有效的加強(qiáng)措施，以確保結(jié)構(gòu)安全、可靠，并具有良好的抗震性能。

Abstract:Wuhan Chenggong Building features tangent angle triangle in building plane. Frame corner columns above 34th floor of the main building have setbacks to form inclined columns and a diamond shape is formed at the top of the building. PKPM and ETABS programs were used to conduct comparison analysis of the structure in the elastic stage,  and SAUSAGE software was used to conduct elastic-plastic analysis of the structure under rare earthquake. On the basis of the out-of-code conditions of the main building,  seismic performance objectives based on integral and components were formulated. And effective strengthening measures were taken for unfavorable structural parts,  weak floors,  shear transfer floors,  inclined columns and starting floor of inclined columns to ensure that the structure was safe and reliable, and had good seismic performance.

Keywords:Wuhan  Chenggong Building; out-of-code high-rise building; inclined column; elastic-plastic analysis under rare earthquake; perforance-based seismic design
