Abstract: Application of spline element and state space method for analysis of dynamic response of elastic rectangular plates is presented.The spline element method is used for space domain and the state space method in control theory of system is used for time domain.A state variable recursive scheme is developed,then the dynamic response of structure can be calculated directly'several numerical examples are given.The results which are presented to demonstrate the accuracy and efficiency of the present method are quite satisfactory.
