摘　　要：介绍了某体育场的看台结构设计内容,通过设置合理的温度缝、温度应力分析及技术措施等,经济有效地解决了看台超长结构温度应力问题;考虑斜塔、环梁斜柱、看台同时工作对看台结构的影响;通过有限元分析验证异形楼梯的设计及传力体系;设置后浇带规避斜塔往复位移对看台结构造成的影响;针对顶层看台大悬挑、低刚度的情况,对舒适度进行分析并优化设计。This paper introduces the structure design of a stadium stand. By setting reasonable temperature crack, temperature stress analysis and technical measures, the problem of temperature stress of super long stand structure is solved economically and effectively. The influence of the simultaneous operation of inclined tower, ring beam inclined column and stand on the stand structure is considered.Through the finite element analysis to verify the design and transmission system of the special-shaped stairs. The post cast strip is set to avoid the influence of inclined tower moving towards reset on the stand structure. According to the situation of large cantilevered and low rigidity of the top stand, the comfort degree is analyzed and optimized.
