摘要
利用通用有限元软件ANSYS,对同一网壳的节点赋予不同的平面外抗弯刚度值,采取与规范规定类似的计算方法,计算网壳的极限承载力,并把节点刚度与杆件的线刚度进行比较,并加以总结,得出一般性规律,对揭示网壳结构的破坏机理具有一定的意义。
In this paper, with the general finite element software ANSYS, it gives the joints different levels of out-plane stiffness values in the same lattice shells and computes the ultimate bearing capacity in the way of rules. By comparing the joints stiffness to the components stiffness, it tries to summarize and draw a general rule, which has certain significance to knowing the failure modes of the single-layer lattice shells.
