［摘要］广州圆大厦建筑立面中部开大洞，采用钢斜撑框架+混凝土核心筒混合结构体系，解决了结构竖向构件不连续的问题。分别采用SATWE和MIDAS/Gen对结构进行弹性分析及弹塑性分析，采用ABAQUS对复杂节点进行有限元分析，最后采用MIDAS/Gen对结构施工阶段进行仿真分析。结果表明结构具有良好的抗震性能，能够满足“强节点弱构件”的要求；施工过程中构件应力水平均较小，且均保持弹性状态，结构受力与预期一致，变形及应力水平均处于合理的范围。［关键词］广州圆大厦; 复杂结构; 节点分析; 施工模拟分析; 钢斜撑框架+混凝土核心筒结构中图分类号：TU318 文献标识码：A 文章编号：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
