| 摘 要： | 大型空间网壳结构设置预应力拉索的目的是减小支座处的水平推力,改善网壳的受力状态,提高网壳结构体系的整体刚度,以提高网壳的承载能力和稳定性。预应力设计是这类结构的关键技术之一。以ANSYS有限元软件为分析平台,详细介绍某体育馆工程有限元分析中探索出的强制性几何非线性分析方法和预应力的调整方法,并提出预应力的调整原则。该方法可为网壳结构预应力设计提供参考。

| Abstract: | The aim to set pre-stressed cable in lattice shell structure is to reduce the horizontal thrust of the support and improve the forced state.It can also strengthen the overall stiffness of the structure and increase its stability and carrying capacity.The pre-stressed design technique has already become the key technique.It is researched the non-linear analysis of the pre-stressed lattice shell structure,and the adjustable method of the pre stress is given.This method can provide guiding principle for prestress design of the lattice shell structure and mechanical analysis. |
