形如深圳大运会体育馆的单层折面网壳结构其基本构形的铰接体系为空间静定桁架结构,为改善该类单层折面网壳的受力性能、提高结构刚度,可在基本体系的基础上增设若干道环杆.对铰接单层折面网壳结构基本体系及环杆加强体系进行进行了全跨、半跨荷载下的静载试验及动力特性试验,并将试验实测数据与理论分析结果进行了比较分析.结果表明,实测数据与理论分析之间差异较小,模型设计和试验方法合理,理论分析方法正确.
For example, the hinged system of single-layer folded reticulated shell structure of Shenzhen Universiade Gymnasium is the static statics truss structure. In order to improve the mechanical properties and improve the rigidity of the single-layer folded reticulated shell, A series of ring-shaped bars were added on the foundation.The static load test and dynamic characteristic test of full-span and half-span load were carried out on the basic system of hinged single-layer reticulated shell structure and the ring-stiffened system, and the experimental data The results of theoretical analysis are compared and analyzed.The results show that the difference between measured data and theoretical analysis is small, the model design and test method is reasonable and the theoretical analysis method is correct.
