五边形三四撑杆全铰接弦支网壳静力及稳定性分析

Jianzhu Gangjiegou Jinzhan
五边形三四撑杆全铰接弦支网壳结构相较于多撑杆索穹顶结构，其核心差异在于通过将索穹顶结构上层脊索转换为脊杆，形成由预应力索与杆组合而成的全铰接曲面双层网格结构体系，该体系既便于刚性屋面铺设，又能降低造价。与传统网壳结构相比，该结构具有良好的稳定性和经济性等特点。在该结构的下弦节点布置3根或4根撑杆，可有效提高整体结构的侧向刚度和稳定性；同时采取铰接节点的连接形式，既能简化节点构造，又便于张拉施工。针对五边形三四撑杆全铰接弦支网壳结构，文中建立了ANSYS有限元模型 ...

五边形三四撑杆全铰接弦支网壳静力稳定性分析

Jianzhu Gangjiegou Jinzhan
五边形三四撑杆全铰接弦支网壳区别于多撑杆索穹顶结构，是将索穹顶结构上层脊索转换为脊杆，形成一种由预应力索、杆组合而成的全铰接曲面双层网格结构体系，便于铺设刚性屋面，减少造价。与传统网壳结构相比，该结构具有良好稳定性和施工便宜性的特点。该结构下弦节点设置三根或四根撑杆，有效提高了整体结构的侧向刚度和稳定性，同时采取铰接节点形式连接，简化节点构造，便于张拉施工。针对五边形三四撑杆全铰接弦支网壳结构，建立ANSYS有限元模型，分析在不同组合工况下该结构索杆内力变化与位移规律。同时 ...
