［摘要］廣州圓大廈建筑立面中部開大洞，采用鋼斜撐框架+混凝土核心筒混合結(jié)構(gòu)體系，解決了結(jié)構(gòu)豎向構(gòu)件不連續(xù)的問題。分別采用SATWE和MIDAS/Gen對結(jié)構(gòu)進(jìn)行彈性分析及彈塑性分析，采用ABAQUS對復(fù)雜節(jié)點(diǎn)進(jìn)行有限元分析，最后采用MIDAS/Gen對結(jié)構(gòu)施工階段進(jìn)行仿真分析。結(jié)果表明結(jié)構(gòu)具有良好的抗震性能，能夠滿足“強(qiáng)節(jié)點(diǎn)弱構(gòu)件”的要求；施工過程中構(gòu)件應(yīng)力水平均較小，且均保持彈性狀態(tài)，結(jié)構(gòu)受力與預(yù)期一致，變形及應(yīng)力水平均處于合理的范圍。［關(guān)鍵詞］廣州圓大廈; 復(fù)雜結(jié)構(gòu); 節(jié)點(diǎn)分析; 施工模擬分析; 鋼斜撐框架+混凝土核心筒結(jié)構(gòu)中圖分類號：TU318 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2016)03-0059-06
Structural design of GuangzhouCircle BuildingJiang Yi, Yi Weiwen（Architectural Design & Research Institute of South China University of Technology, Guangzhou 510641, China）Abstract:Guangzhou-Circle Building has a big hole on center of the faade and adopts steel braced frame-corewall structural system which solves the vertical discontinuity problem of structural members. Programs of SATWE and MIDAS/Gen were used to carry out elastic and elasto-plastic analyses on the structure. ABAQUS software was used to conduct finite element analysis on complicated joints. Finally MIDAS/Gen software was used to carry out construction simulation analysis. Results show that the structure has good seismic performance and can meet the requirements of the "strong joint and weak component". In construction process, components have small average stress levels and are in elastic states. The mechanism of the structure is the same as expected results and the deformation and stress levels are in a reasonable range.Keywords:Guangzhou-Circle Building; complicated structure; joint analysis; construction simulation analysis; steel braced framecorewall structure
