| description | To resolve trade-off between model accuracy and computational complexity in numerical analysis that simulates an extraction test for underground structures.SOLUTION: A structure model generation unit 11 generates a structure model that models underground structure. A particle generation unit 12 sets the maximum diameter of an SPH particle, which does not cause time history results that underestimate the pull-out resistance of analysis results, to generate the SPH particle for modeling soil that is a support body of the underground structure. An arithmetic unit 14 performs coupled analysis of the structure model and the SPH particle by a finite element method and an SPH method.SELECTED DRAWING: Figure 1
【課題】地中構造体の引抜き試験を模擬する数値解析において、モデルの精度と計算量のトレードオフを解決する。【解決手段】構造体モデル生成部１１が地中構造体をモデル化した構造体モデルを生成し、粒子生成部１２が、解析の結果の引抜き抵抗力が過小評価されるような時刻歴結果を示すことが生じることのない最大のＳＰＨ粒子の径を設定して、地中構造体の支持体である土壌をモデル化したＳＰＨ粒子を生成し、演算部１４が有限要素法とＳＰＨ法により構造体モデルとＳＰＨ粒子を連成解析する。【選択図】図１ |
