長方形基礎の Dynamical Ground Compliance (その1) ―半無限弾性地盤の場合―

Abstract

It is the purpose of this paper to study the properties of "Dynamical Ground Com-pliance" of a semi-infinite elastic medium. Representing its Compliance as the ratio ofthe displacement of a rectangular foundation to a harmonic disturbing force acting onthe foundation, it corresponds to the transfer function of the elastic ground. The an-alytical results show that Dynamical Ground Compliance is expressed by the complexnumber, the imaginary part of which is concerned with the phenomenon of the energydispersion caused by the wave propagation outside the foundation, and that it dependson the ground constants, the shape and dimension of the foundation area, and the frequencyof a disturbing force.
