Abstract
The theoretical method has been explained in previous paper, to analyze on basis of three-dimensional wave propagation theory the dynamic characteristics of a structure with rounded corners rectangular section, which was embedded in surface stratum on Bed Rock. And equivalent circular radius for square section structure was evaluated. This paper describes the following items for above-mentioned embedded rigid structure with rectangular section. (i) Relation between dynamic characteristics and shape of structure. Difference between dynamic characteristics in short direction of rectangular section structure and that in long. (ii) Application of two-dimensional analysis to evaluation of the dynamic characteristics in short direction.
