（天津市房屋鉴定建筑设计院，天津 300070）［摘要］天津静海团泊足球场采用由混凝土看台及钢结构罩篷组成的混合结构体系，看台设置型钢混凝土柱作为罩篷悬挑桁架的支座。为了真实模拟结构的整体刚度和自振特性，将混凝土看台及钢结构罩篷作为整体结构进行空间分析。基于工程实践，全面介绍结构设计中的关键问题，包括主桁架屋顶罩篷支座形式，设置预应力优化杆件截面、减小悬挑端挠度，假定塔柱与主桁架间的拉杆失效进行结构防倒塌分析。采用有限元软件对结构进行静力非线性、弹性反应谱、弹性时程、屈曲模态分析，验证了结构的安全、稳定、合理性。［关键词］悬挑桁架; 预应力; 防倒塌分析中图分类号：TU318 文献标识码：A 文章编号：1002-848X(2015)05-0021-04Structural design of Tuanbo Football Stadium in Jinghai in TianjinFeng Limei, Wang Dawei, Tang Peng(Tianjin Real Estate Appraise Survey & Design Institute, Tianjin 300070, China)Abstract: Tuanbo Football Stadium in Jinghai in Tianjin adopts mixed structural system composed of concrete stand and steel canopy structure with steel reinforced concrete columns in stand as supports for cantilever truss of the steel canopy. In order to simulate the whole structure stiffness and the natural vibration characteristics of the structure, the concrete stand and steel canopy were analyzed as a whole spatial structure. Based on the engineering practice, key problems in structural design were introduced, including the form of roof canopy support for the main truss, optimization of member section and decrease the cantilevered end deflection through exerting pre-stress, anti-collapse analysis through assuming the failure of pull rods between the main truss and columns. By using finite element software, the static nonlinear analysis, elastic response spectrum analysis, elastic time-history analysis and buckling modal analysis were carried out to verify the security, stability and rationality of the structure.Keywords: cantilever truss; pre-stress; anti-collapse analysis作者简介：冯莉梅，高级工程师，Email:rd70710@vip.sina.com。参考文献［1］刘志伟，张晓新．锦州滨海体育中心体育场结构设计［J］．建筑结构，2013，43（9）：29-32.［2］马克俭，肖建春，刘晨，等．贵阳奥体中心体育场挑篷预应力设计建议［J］．贵州工业大学学报：自然科学版，2008，37（4）：1-5.［3］陈志华，肖骁，刘红波. 太阳辐射作用下钢管温度计算简化方法［J］．天津大学学报：自然科学与工程技术版，2014，47（增刊）：1-7.［4］王红涛，徐珂，田立强．某体育场罩篷钢结构设计［J］．钢结构，2012，27（6）32-36.［5］傅学怡，杨想兵，高颖，等．济南奥体中心体育场结构设计［J］．空间结构，2009，15（1）：11-19.［6］陈肇元，钱稼茹．建筑与工程结构抗倒塌分析与设计 ［M］．北京：中国建筑工业出版社，2010.
