This paper classifies the analysis methods of stochastic structures, and briefly describes the basic solving process of stochastic structural analysis methods proposed in recent years. The determination of the distribution of random variables in random structure analysis, the handling of random loads and the processing of the correlation of random parameters are discussed. The stochastic factor method is applied in the structural analysis and boundary condition processing, dynamic characteristics and dynamic response analysis, stochastic vibration response analysis and dynamic reliability analysis, dynamic analysis of smart structure in open-loop and closed-loop state, stochastic steady state and transient Temperature field analysis and the random parameter structure under the random heat load response analysis and many other aspects are reviewed.
