| 摘 要： | 首先用单源随机向量表达复杂的随机结构系统的随机变量,使整个系统的基本随机变量减少到1个,然后阐述随机结构的表达方法,最后以两杆桁架结构为例,进行极限承载力分析.算例表明了这种单源分析方法的有效性.该方法的特点:表达随机结构只需一个随机变量;随机结构的表达式是关于单源随机向量的线性展开式,可由此计算结构的概率特征.

| Abstract: | This paper expresses the basic random variables of a complex structure system with monophyletic random vector,reduces the number of the basic random variables down to 1.Then it introduces the method of expressing a stochastic structure,and computes the limit bearing capacity of a truss structure with two bars as an example.The calculation results show the effectiveness of the monophyletic analysis method(MAM).There are two characteristics of this method: expressing a stochastic structure only needs one rand... |
