摘要
本文从预应力空间钢结构的优越性和特点出发,构想了一种新型的上、下弦为预应力张索的组合网架结构。讨论了基于概率的“以性能为基础”的设计思想,探讨了工程结构可靠性分析的蒙特卡罗(Monte Carlo)有限元法,分析了蒙特卡罗(Monte Carlo)有限元法的基本原理及其在ANSYS程序上的实现过程,并在ANSYS程序上对该张索结构进行静力计算和可靠性分析。
Based on the prestressed tensegrity structure and the grids structure ,this paper has suggested a new cooperative grids composed of prestressed cables and poles.And it has dicussed the based-on-performance design idea which is based on probability and Monte Carlo method in which engineering reliability is analyzed.Also has finished statics analysis and reliability analysis in ANSYS.
