| 摘 要： | 针对只受拉单元一般平衡方程应用中经常遇到的迭代发散或总刚奇异情况，提出了只受拉单元的修正平衡迭代方程。采用该方法，可以在计算含只受拉单元的轻钢厂房柱间支撑及大型复杂结构体系时快速得到收敛解。

| Abstract: | In this paper the modified equilibrium iterative equation for tension-only elements is presented for mechanical analysis of structural systems. The modified equation can be used instead of the traditional normal equation for tension-only members, which usually causes the total stiffness matrix odd or can not lead to the convergence results. The computation using modified equation can quickly converge to satisfactory results. |
