摘要
长葛体育馆主体结构为平面不规则的超长结构,看台为阶梯形布置,没有明显的结构层,屋面为空间正交平面桁架体系。不规则结构一般会产生较大的扭转效应,超长结构内力和变形受温度作用效应的影响不能忽视。综合考虑了各种复杂因素,对结构设计提出了具体的分析方法。对结构体系进行了整体和局部分析,提出了温度作用的计算方法和构造措施。
The main structure of Changge Gymnasium is a plane irregular super-long structure. Stands for the ladder type are decorated,no obvious layer structure. Roof system is space orthogonal plane truss. Irregular structure tends to produce bigger torsion effect. Super-long structural internal force and deformation are affected by temperature effect which cannot be ignored. Considering various complex factors,specific analysis method on structure design was put forward. The overall and local analyses for structure system were conducted. The calculation method of temperature effects and structural measures were put forward.
