Simply Supported Rectangular Plates under Random Loads

This paper deals with the problem of simply supported rectangular plate that is subjected to tranverse loads distributed statically at random, and shows the computing methods of following problems. 1) Mean values and variances of stress and deflection of these loaded plates. 2) Sum of square of the natural periods of unloaded rectangular plate (T=Σt_i). 3) Mean and variance of T under random loads.
