| 摘 要： | 建立了桁架结构的有限元分析模型。采用蒙特卡罗法(Monte-Carlo Method),分析了输入随机变量对桁架可靠性的影响。结果表明:杆件横截面积对单元A1轴向应力的影响较大,是影响桁架失效概率的主要因素;同时单元A1的横截面积对桁架结构体积的变化起主要作用。

| Abstract: | The finite element analysis model of truss structures was established.Based on the Monte-Carlo method,the effect of input stochastic variables on the truss reliability was analysed.The results indicate that cross-section area of bar have great influence on axial stress of the unit A1,it is the main influence factors on failure probability the truss;and the cross-section area of the unit A1 plays main role on change of truss structural volume. |

| Keywords: | reliability Monte-Carlo method effective stress axial stress |
