| 摘 要： | 空间结构中常用的节点多数都是介于刚接和铰接之间的一种半刚性节点。国内对用于空间结构中的半刚性节点以及半刚性节点网壳的研究目前还比较少。基于半刚性节点的试验研究,得到了螺栓球半刚性节点在弯矩荷载和压弯荷载共同作用下的弯矩-转角曲线。利用大型通用有限元分析软件ANSYS建立了用于空间半刚性网壳结构的有限元分析模型。最后,将由试验得到的节点的弯曲刚度带入半刚性凯威特单层网壳的数值模型中,考虑几何参数和节点刚度对半刚性网壳稳定性的影响,展开了大规模的弹塑性全过程分析,通过系统的参数分析,较为全面地掌握了半刚性单层网壳的稳定性能,并进一步总结得出了螺栓球半刚性节点单层球面网壳的稳定承载力公式。

| Abstract: | Most of the joints in spatial structures are semi-rigid joints whose behaviors are between that of the rigid joint systems and pin joint systems.However,for spatial structures,the existing references on the behaviors of semi-rigid joints are limited.Firstly,the two experimental programs in this paper are designed to obtain the moment-rotation curves of the bolt-ball semi-rigid joints subjected to two loading cases:bending with and without the axial compressive force.Secondly,based on the moment-rotation cur... |
