摘要
北京某全民健身中心项目主要包括篮球馆、游泳馆和冰球馆3个分区,地上平面尺寸197m×100m,各个功能分区之间连成整体,采用同一建筑屋盖结构。首先结合建筑方案对各子项中大跨度楼盖、屋面和主体结构进行了结构选型和可行性分析。随后,对结构进行体系计算验证及超限判别,并根据判别结果提出了针对扭转不规则、楼板不连续和复杂连接选用的设计措施。研究及设计结果表明:通过选用合理的结构设计方案,提出的钢结构屋面基本可以满足规范相关设计要求,结构安全、可靠,结构设计可行。
A National Fitness Center project in Beijing mainly includes three sub-zones:basketball gymnasium,swimming pool and ice hockey gymnasium.The above-ground plane size is 197 m×100 m.Firstly,combined architecture scheme,the structure selection and feasibility analysis of the long span floor and roofing system was explained.Then,the irregular judgment of the main structure is operated and the design measures about the irregularity of the structure are introduced systematically.Subsequently,the structure was verified by system calculation and over-limit judgment,and based on the judgment results,design measures for torsion irregularities,discontinuous floor slabs and complex connections were proposed.The research and design results show that by selecting a reasonable structural design scheme,the proposed steel structure roof can basically meet the relevant design requirements of the code,the structure is safe and reliable,and the structure design is feasible.
