［摘要］武漢長江航運(yùn)中心大廈結(jié)構(gòu)地上62層、地下4層，建筑高度330m，經(jīng)過方案比選采用鋼筋混凝土框架-核心筒結(jié)構(gòu)體系，為武漢地區(qū)類似高度超高層建筑首例。從抗震概念設(shè)計出發(fā)，采用性能化抗震設(shè)計對主要構(gòu)件進(jìn)行復(fù)核，采用PMSAP及SAP2000軟件進(jìn)行小震、中震驗算，采用PERFORM\|3D軟件進(jìn)行大震下結(jié)構(gòu)彈塑性時程分析，還進(jìn)行了塔冠部分剛架非線性穩(wěn)定分析、結(jié)構(gòu)抗連續(xù)倒塌分析、樓板地震應(yīng)力分析、人行荷載及風(fēng)荷載作用下舒適度分析、混凝土長期徐變收縮影響分析。結(jié)果表明，此結(jié)構(gòu)方案具有較高的抗震承載能力和延性，能夠滿足現(xiàn)行各項規(guī)范的要求。

Abstract:Wuhan Changjiang Shipping Center is a frame-core wall structure system with the height of 330m and consists of 4 stories underground and 62 stories overground. After the program comparison, the reinforced concrete frame-core tube structure system was adopted, which is the first case among similar height high-rise building in Wuhan. From the seismic conception, performance-based design was used to review the main components. PMSAP and SAP2000 software were used for small and middle earthquakes seismic inspection. PERFORM-3D software was used in elastic-plastic time-history analysis under rare earthquake. Besides, nonlinear stability analysis of tower crown steel structure, progressive collapse analysis, stress analysis of floors and comfort analysis under pedestrian load and wind load were put out. The results show that the structure has sufficient seismic capacity and ductility, which can meet the requirements of the existing codes．
Keywords:Wuhan Changjiang Shipping Center； out-of-codes high-rise building; elastic-plastic time-history analysis; nonlinear stability analysis; progressive collapse analysis; comfort analysis; concrete shrinkage and creep
