Research Development for the Orthogonal Expansion Method of Stochastic Structural Analysis

The building of modern complex structure helps to bring about the research development of stochastic structure analysis.In the past ten years,the orthogonal expansion method for stochastic structure analysis present a new technology for the dynamic analysis and modeling of stochastic structure.This paper summarizes the expanded order system method developed by the author in the past few years.Some case studies are given in the paper to show the application of expanded order system method on the common building engineering structure.These examples show that the failure probability of structures will be changed remarkably from the viewpoint of structure analysis.
