Description

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. (author)

Abstract (Japanese)

地盤-構造物相互作用を考慮した地震応答解析を行うため,従来,構造物と地盤に質点系モデルと地盤ばねモデルが使われていた.本研究は,メタモデリング理論を基に,従来のモデルの解釈を試みる.連続体力学理論に基づく構造物地盤の地震応答を,物理的な仮定を設けず,数理的な近似のみで解くという解釈である.この解釈に基づき,質点系モデルはもとより地盤ばねモデルのばね定数等のパラメータを合理的に決定できることを示す.これは,従来のモデルを使う地震応答解析が有限要素法モデルを使う地震応答解析を近似しうることを意味する.簡単な構造物と地盤の地震応答解析に対して数値実験を行い,本論文で考える従来モデルの解釈の妥当性を検証した.(著者)
