| 摘 要： | 基于随机安装偏差模式，利用空间有限单元法和概率方法，分析了网架结构由于安装偏差引起的初始应力和初始位移。倒放四角锥网架的算例结果表明，随机安装偏差对网架结构的承载力有较大的影响，不可忽视。提出的思路和方法对空间网架结构的设计有参考价值。

| Abstract: | Based on the assumption of random installation deviation, the finite element met hod analyzing the initial displacement and stress of grid structures was set up. The random installation deviation was assumed as normal distribution. Numerical example showed that the random installation deviation had a large effect on the safety of the grids structures and could not be ignored. It also showed that th e method obtained was significant for the design of grids structures. |
