（北京市建筑设计研究院有限公司， 北京 100045）［摘要］宿州体育馆主场馆平面尺寸为120m×135m，地上3层，为大跨空间结构，下部主体结构采用钢筋混凝土框架剪力墙结构体系。大跨曲屋面采用双向正交正放平面桁架体系。设计时对结构进行了风洞试验和地震安全性评价，按抗规方法考虑了屋盖竖向地震作用，考虑了大跨屋盖温度效应的影响，对支承屋盖的框架柱进行了中震设计，研究分析了相贯节点的构造加强措施，并采用ABAQUS软件对相贯节点进行了强度和稳定分析；采用PMSAP，MIDAS软件对整体结构进行了计算分析，两种软件计算结果均满足现行规范要求。［关键词］宿州体育馆; 大跨空间结构; 相贯节点; 有限元分析中图分类号：TU393.3 文献标识码：A 文章编号：1002-848X(2014)20-0099-06Structural design of Suzhou GymnasiumLiu Lijie, Li Jungang, Gao Pengfei(Beijing Institute of Architectural Design, Beijing 100045, China)Abstract: Suzhou Gymnasium, which has the plane size of 120m×135m, is a large-span spatial structure with two layers on the ground and adopts reinforced concrete frame-shear wall structure for the lower main structure. The large-span curved roof adopts two-dimensional orthogonal planar truss system. The wind tunnel test and the earthquake safety evaluation were carried out in design. The vertical earthquake action was considered according to the code and temperature effect of large-span roof was considered. The medium seismic design of the frame columns supporting roof was carried out. Besides, the construction strengthened measures of tubular joint were studied and ABAQUS software was used to analyze its strength and stability. The PMSAP and MIDAS software were used to analyze the over-all structure. The calculation results of two kinds of software can satisfy the requirements of the current code.Keywords: Suzhou Gymnasium; large-span spatial structure; tubular joint; finite element analysis作者简介：刘立杰，博士，高级工程师，Email:liulj1673@126.com。参考文献［1］GB 50011—2010建筑抗震设计规范［S］. 北京:中国建筑工业出版社, 2010.［2］GB 50009—2001建筑结构荷载规范［S］. 2006年版.北京:中国建筑工业出版社, 2006.［3］JGJ 7—2010空间网格结构技术规程［S］. 北京:中国建筑工业出版社,2010.［4］GB 50017—2003钢结构设计规范［S］. 北京:中国计划出版社, 2003.［5］吴亮秦,李自林,韩庆华. 垫板加强N形圆钢管相贯节点静力性能试验研究［J］.建筑结构学报,2010,31(10)：83-188.
