STUDY ON CONVENTIONAL SEISMIC RESPONSE ANALYSIS MODEL WITH SOIL-STRUCTURE INTERACTION BASED ON META-MODELING THEORY

Abstract

Mass Spring-Soil Spring (MSSS) model has been used for seismic response analysis that accounts for soil-structure interaction. This paper seeks to interpret the basic concept of this modeling, based on the meta-modeling theory. It is shown that the MSS model is a mathematical approximation of continuum modeling, without introducing any physical assumption. The values of the mass and spring constant of MSS model is rationally determined. Numerical experiments for a set of simple structure and soil supports the validity of the interpretation of the MSSS model made by this paper.
