摘要：
The finite element method (FEM) with the concept of probability theory was used to determine structural responses of complex structures. The statistical changes in natural frequencies and mode shapes were integrated by using FEM techniques of the original model. The method was applied experimentally to cantilever aluminum beam for two test cases with actual modulus of elasticity equal to 5%.
