摘　　要：某高级中学体育场采用钢筋混凝土框架结构,通过4道永久伸缩缝分成4个独立单元;其中东西结构单元看台设置钢结构挑篷,南北结构单元为露天看台。文章系统介绍了体育场的设计过程,主要有结构方案的选型、钢屋盖结构体系的布置及风荷载体型系数的取值,并采取多模型对其进行包络设计。利用3D3S软件对看台挑篷在各种工况作用下的内力和变形进行了计算分析,分析结果表明,挑篷结构受力合理,满足设计要求。根据抗震性能目标,对本工程进行了抗震性能化设计。对超长结构进行温度作用的计算分析,并采取有效措施来解决温度变化和混凝土收缩对结构的影响。Reinforced concrete frame structure is adopted in a senior high school stadium,which is divided into four independent units through four permanent expansion joints.The east and west structural unit stands are set up with steel structure canopy roof,and the south and north structural units are open-air stands.The design process of stadium were systematically introduced in this paper,mainly including the selection of structural scheme,the arrangement of steel roof structural system and the value of wind load shape coefficient,and envelope design were carried out by multiple models.The internal force and deformation of the grandstand canopy under various working conditions are calculated and analyzed by using 3D3S software.The analysis results show that the stress of the canopy roof structure is reasonable and meets the design requirements.According to the seismic performance target,the seismic performance-based design is carried out for the project.The temperature effect of super long structure is calculated and analyzed,and effective measures are taken to solve the influence of temperature change and concrete shrinkage on the structure.
