| 摘 要： | 提出用大位移带刚臂杆元来考虑节点大小对网壳结构承协性能的影响，推导出大位移带刚臂元的影响矩阵，修正了Ｃ．Ｏｒａｎ的梁一柱单元切线刚度矩阵，并对类似的支座节点体进行了同样的推导修正，通过对网壳结构算例的分析计算，证明了文中理论的正确可靠。

| Abstract: | The effects of the joint size of the reticulated shell on the loading capacity are discussed in this paper. The influence matrix of the large displacement element with rigid arms is first derived. The tangent stiffness matrix of Oran's beam-- column element is revised. And the similar support joints are also updated. Through computing several numerical examples, it is proved that the theory in the paper is correct and reliable. |
