| 摘 要： | 在动力荷载作用下单层网壳结构杆件受力和结构承载力处于动态变化中,因此要得到准确的结构实时动力响应,必须建立能够模拟杆件实时受力性能的杆件计算模型.根据单层网壳结构杆件的受力特点,总结出受压杆件的两种失稳类型.引入国际标准化组织推荐的空间受力圆钢管失稳判别准则,采用3节点塑性铰单元和Marshall模型分别模拟受压杆件失...

| Abstract: | Under dynamic excitation,the loads imposed on the members of the single-layer latticed shells change continuously,resulting in the change of load carrying capacity of the structure.The numerical model for the simulation of the real time mechanical behavior of the member is necessary,to obtain the accurate real time dynamic responses of structures.Based on the mechanical characteristics of the single-layer latticed shell member,two buckling types for compression members were summarized.The buckling criterion... |
