| 摘 要： | 利用有限元分析软件ANSYS进行参数化编程建模,对带有屈曲约束支撑的单层落地椭球网壳的减震性能进行分析.假设屈曲约束支撑杆件为理想弹塑性,在三维El-Centro波和Taft波作用下对结构进行动力响应分析.计算结果表明,屈曲约束支撑构件对网壳结构关键点的位移和杆件内力响应明显减小.对不同的屈曲约束支撑布置方案进行对比分析,得出屈曲约束支撑布置的主要原则. |

| Abstract: | With the help of the software of nonlinear finite element analysis ANSYS to perform the modeling with parametric programming,monolayer grounded ovaloid shell with buckling-restraining braces was analyzed.On the assumption that the material of the braces would be perfectly elastic-plastic,the dynamic response of this structure to the 3-dimensional El-Centro and Taft waves was analyzed.The computation result showed that the displacement and internal force response of the key-points in the shell structure with... |
