摘要
本文讨论了变厚平板型网架的差分计算法。按网架结构的平衡和变形条件,给出了分配节点荷载公式,进而可以计算网架内力。为便于说明,最后提出了一个数值算例。
Finite difference method of space truss with variable thickness is discussed in this paper. According to the conditions of deformation compatibility and equilibrium at the node of orthogonal space truss, the distributed load formulas are obtained. In addition, numerical example is given.
