王继涛,张作运,周廷垣,师瑜莹,刘辰(中国中元国际工程公司,北京100089)[摘要]对新疆伊南工业园造型奇特的入口结构进行分析,研究了弧形桁架内扭矩对杆件内力分布的影响、温度效应的释放以及水平和竖向地震对结构的影响等问题,对比了结构各部分的单体分析与整体结构的整体分析在地震及温度作用下的反应,以确定地震及温度作用在结构中比较真实的效应,从而弥补各个部分单独计算及支座假定不合理所带来的不利影响,为此类结构的设计提供参考。[关键词]弧形桁架; 空间结构; 整体分析; 单体分析中图分类号:TU393.3 文献标识码:A 文章编号:1002-848X(2013)03-0055-04Analysis on structural design of the entrance structure of Yinan Industrial Park in XinjiangWang Jitao, Zhang Zuoyun, Zhou Tingyuan, Shi Yuying, Liu Chen(China IPPR International Engineering Corporation, Beijing 100089, China)Abstract: The entrance structure of Yinan Industrial Park in Xinjiang was analyzed, the shape of which is unusual. Studies on influence of member internal force distribution from arc truss inner torque, release of temperature effect and impact on structure from horizontal and vertical earthquakes were made. By the comparison of the result of whole structural analysis and separate structural analysis for this structure under the action of earthquake and temperature, necessity of the whole structural analysis is proved to achieve real response of the structure and avoid the defect of the separate structural analysis, which can serve as a reference for other similar projects.Keywords: arc truss; spatial structure; whole structural analysis; separate structural analysis作者简介:王继涛,硕士,工程师,Email:wangjitao@ippr.net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]傅学怡,高颖,杨想兵.总装分析对大跨空间结构设计的重要性[J].空间结构,2009, 15(1):3-10.[3]北京金土木软件技术有限公司.SAP2000中文版使用指南[M].北京:人民交通出版社,2006.
