(1中國建筑設(shè)計研究院，北京100044；2北京通宸建筑設(shè)計有限公司，北京100048)[摘要] 東勝網(wǎng)球館為體育公共建筑，主體結(jié)構(gòu)由十榀異形直立拱式剛架和兩榀分別向外傾斜的斜向異形拱式剛架組成。拱式剛架采用實腹式開圓孔H型鋼截面，拱式剛架之間布置系桿與交叉支撐，與拱式剛架共同構(gòu)成穩(wěn)定的結(jié)構(gòu)體系。主體結(jié)構(gòu)的跨度為47m，大跨度開圓孔H型鋼拱式剛架的設(shè)計是本工程設(shè)計的難點和關(guān)鍵點。本文對主體結(jié)構(gòu)進行了整體分析和設(shè)計，并利用通用商業(yè)軟件ANSYS對開圓孔拱式剛架的穩(wěn)定性進行了分析，旨在探明拱式剛架結(jié)構(gòu)的受力特點和設(shè)計要點。[關(guān)鍵詞] 拱式剛架；開圓孔；大跨度；穩(wěn)定性；有限元方法；中圖分類號：TU398.7 文獻標識碼：A 文章編號：1002-848X(2013)S1-0311-05作者簡介：劉學林，博士，高級工程師，一級注冊結(jié)構(gòu)工程師，Email: liuxl@cadg.cn。Analysis and Design of Main Structure of Dongsheng Tennis StadiumLiu Xuelin1，F(xiàn)eng 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
