The analysis methods of finite element for fuzzy truss structures under fuzzy loads action are developed. Based on the information entropy, the fuzzy variables are transferred into random variables, where the structural physical parameters and geometrical dimensions and applied loads are all considered as fuzzy variables. According to the random factor method (RFM), the computational expressions of the mean value and mean variance of the structural displacement response and stress response are deduced by algebra method. The influences of the fuzziness of the structural physical parameters and geometric dimensions and loads on the structural displacement and stress response are analyzed via some examples, and the rationality and feasibility of presented model and approach are validated, the advantage of the proposed method is that the influence of the fuzziness of each parameter on the structural response can be reflected.

A research on analytical method of structural dynamic characteristics aimed at fuzzy truss structure is given.

研究了模糊桁架结构动力特性的分析方法,在结构的物理和几何参数同时为模糊变量的情况下,利用模糊因子建立了结构的刚度矩阵和质量矩阵;从结构振动的瑞利商表达式出发,利用区间运算法则推导出结构模糊特征值的表达式。通过算例考察了结构各参数的模糊性对其动力特性模糊性的影响,并获得了一些有意义的结论。该法对模糊结构进行一次动力分析便可求得动力特性,且可充分地反映任一模糊参数对结构模糊动力特性的影响。
