Abstract

The governing differential equations for free vibration of a one-step shear plate and a multistep shear plate are established. It is shown that a shear plate can be divided into two independent shear bars to determine the natural frequencies and mode shapes of the plate. The jkth natural frequency of a shear plate is equal to the square root of the square sum of the jth natural frequency of a shear bar and the kth natural frequency of another shear bar. The jkth mode shape of the shear plate is the product of the jth mode shape of a shear bar and the kth mode shape of another shear bar. In this paper, two methods - transfer matrix method and recurrence formula method - are proposed to determine the natural frequencies and mode shapes of multistep shear plates. A numerical example shows that the present methods are easy to implement and are efficient. © 2000 Sage Publications, Inc.
