(浙江大学建筑设计研究院,杭州 310027)[摘要]浙江大学新校区体育馆钢结构屋盖是由桅杆斜拉索网系统、钢结构屋盖系统、周边支承钢柱系统以及低屋面周边挑檐系统四部分构成,整个结构新颖独特,体系比较复杂。采用多个计算软件对该结构体系进行整体及局部的计算和分析,较为准确地得到了结构体系的受力特征和变形情况,合理布置各处截面,优化了设计。[关键词]桅杆斜拉索网;钢结构屋盖;外倾圆管柱;挑檐Analysis of design for steel roof structure of ZJU′s new campus gymnasiumJin Zhenfen, Shen Jin, Qiu Tao, Cao Yunzhong(Architectural Design & Research Institute of Zhejiang University,Hangzhou 310027, China)Abstract:The steel roof structure of the new campus gymnasium of ZJU is composed by four parts, including the system of suspended cable net oblique mast, steel roof structure, circumjacent bracing column and circle projecting cornice of low roof. The whole structure is complex. Various calculation methods are used to calculate and analyze the structure, to get the reinforce power character and distortion condition accurately. And the optimization of the member sections are carried out.Keywords:oblique mast suspended tension cable-net; steel roof stricture; extraversion column; projecting cornice作者简介:金振奋,硕士,一级注册结构工程师,Email:jinzf@zuadr.com。参考文献[1]GB50017—2003 钢结构设计规范[S].北京:中国计划出版社,2003.[2]GB50011—2001 建筑抗震设计规范[S].北京:中国建筑工业出版社,2001.[3]GB50018—2002 冷弯薄壁型钢钢结构设计规程[S].北京:中国计划出版社,2002[4]建筑用铸钢节点技术规程(征求意见稿,2006年4月).[5]浙江大学紫金港校区文体中心体育馆风洞试验报告[R].杭州:浙江大学空间结构研究中心.
