(1中国建筑设计研究院，北京100044；2北京通宸建筑设计有限公司，北京100048)[摘要] 东胜网球馆为体育公共建筑，主体结构由十榀异形直立拱式刚架和两榀分别向外倾斜的斜向异形拱式刚架组成。拱式刚架采用实腹式开圆孔H型钢截面，拱式刚架之间布置系杆与交叉支撑，与拱式刚架共同构成稳定的结构体系。主体结构的跨度为47m，大跨度开圆孔H型钢拱式刚架的设计是本工程设计的难点和关键点。本文对主体结构进行了整体分析和设计，并利用通用商业软件ANSYS对开圆孔拱式刚架的稳定性进行了分析，旨在探明拱式刚架结构的受力特点和设计要点。[关键词] 拱式刚架；开圆孔；大跨度；稳定性；有限元方法；中图分类号：TU398.7 文献标识码：A 文章编号：1002-848X(2013)S1-0311-05作者简介：刘学林，博士，高级工程师，一级注册结构工程师，Email: liuxl@cadg.cn。Analysis and Design of Main Structure of Dongsheng Tennis StadiumLiu Xuelin1，Feng Jingwen2(1 CHINA Architecture design & Rearch Group，Beijing 100044，China；2 Beijing TongChen Architecture design Co. Ltd，Beijing 100048，China)Abstract: Dongsheng tennis stadium is a sports public building. Main structure is made up of ten special-shaped arch frames and two oblique arch frames which are leaning outside fifteen degrees and ten degrees respectively. By using H-shape solid-web steel beam with circular holes, tied rods and cross supported members are planned between the arch frames. The arch frames become stable structural system. The span of the main structure is 47 meters long span which is difficulty and key points in the design of the project. Aiming to ascertain the behavior and design key points of arch structures, this paper analysis the main structures comprehensively. The stability of arch frames with circular holes is analysis by ANSYS.Keywords: Arch frame; with circle hole; long-span; stability; finite element method
