Abstract Plates structures have been extensively used in many industrial fields conducted to a variety of civil, mechanical, aeronautical and architectural engineering constructions. The dynamic inter-action between the floor and the excitations has attached special interest recently. Due to the difficulties of the analytical solutions of the plate problems, very few analytical solutions are available and limited to the simply supported condition of plate. Thus, numerical methods are used to overcome these difficulties. Finite element and finite difference methods are conducted to a large matrix of simultaneous equations when either of them is used alone or combined with the finite strip technique. To overcome the disadvantage of the finite strip method based on a technique conducted to a large number of algebraic equations, the new present method is used. The new present method, Finite Strip Transition Matrix method FSTM, is a hybrid procedure which combines the advantages of the series solution of partial differential equation of orthotropic plate and transition matrix method. The transition matrix, which is utilized to develop the new FSTM technique, has been derived from the Runge-Kutta method for the fourth order ordinary differential equation. |
