摘要
利用结构力学中的力法原理,对预应力钢桁架进行了理论分析,在此基础上建立了钢桁架杆件和拉索的可靠性分析模型,然后利用一次二阶矩法求解了可靠度指标β,最后以常见的预应力钢屋架为例,分析了其上拉索和杆件的可靠度。
Using the force method principles of structural mechanics, it makes the theoretical analysis to the prestress steel truss, on base of it, it builds the reliability analysis model of steel truss member bar and dragline, then using the linear second-order matrix method it solves the reliability index β, and setting the common prestress steel truss as example at last, it analyses the reliability of the dragline and bar.
