矩形基礎の Ground Compliance とその Simulation について

Abstract

In considering the earthquake response of buildings and other above-ground structures, itis very important to know the ground compliance for the foundation configuration. Recentlythe study on the dynamical compliance of the rectangular foundations was presented by Prof.W. T. Thomson and T. Kobori, and also has been extended by authors and Mr. T. Suzuki.In this paper, the simulation method of this problem to analog computer is, in general, deve-loped for arbitrary excitations. Based on the conditions both of physical realizability andmathematical stability, the transfer function of ground compliance is approximately expressedby the rational function and replaced with the equivalent electronic analog circuit. Finally thegood approximation of this simulation method is shown as an example.
