摘要
基于"海南球"工程的设计实例,总结了大跨度肋环斜杆型单层网壳的结构计算及设计要点。对该工程结构形式的选取、单层网壳的稳定性、抗震性能以及单层网壳开大洞口的补强方案进行了论述。重点对该工程的稳定性进行详细的计算分析,讨论了初始缺陷幅值对整体结构稳定性的影响,并给出初始缺陷幅值合理取值的一些建议。
Taking the design of Hainan Ball for example,the key points of the overall structural design and calculation were summarized for the schwedler type single-layer lattice shell structure.The structural type selection,stability of the single-layer lattice shell,seismic performance and the reinforcement solution of a large hole opened in the project were discussed.The nonlinear-overall stability analysis of the project was carried out,and the impact of the amplitude of initial imperfection on the overall stability was analyzed.Some recommendations of the reasonable value of the amplitude of initial imperfection were given.
