[摘要]某直径33m单层球形网壳采用了无缝钢管作为主要网壳杆件,并结合建筑美观需求,其杆件汇交处的节点采用了新型板拼型焊接节点。重点介绍了该汇交节点在网壳弹性受力及几何非线性受力模态下的节点有限元分析及其应力分布特点,也印证了其安全可靠的传力机制,可为同类网壳节点形式的推广应用提供参考。

Abstract: The diameter of a single layer latticed shell is 33 meters, which adopts the seamless steel tube component. The joint of the single layer latticed shell is a new type. The safety of the node in the elastic force and geometric nonlinearity was introduced, which can provide reference for the the same kind of the shell joint.
Keywords: single layer latticed shell; latticed shell joint; new type joint; finite element analysis; geometric nonlinearity
