| Abstract: | This paper discusses the anlaysis method of stochastic structural system with deterministic excitations. A general formulation suitable for the dynamic anlaysis of linear multi -degree of freedom stochastic structural system is established. This can be used for various kinds of systems which possess combinations of random mass damping and stiffness parameters. A recursive condensation algorithm for solving the equation of expanded order system is put forward. |
