Title:
ANALYSIS DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/255709
Kind Code:
A1
Abstract:
The present invention resolves a tradeoff between the precision of a model and the amount of calculation in a numerical analysis that simulates pullout testing for an underground structure. A structure model generation unit 11 generates a structure model modeling an underground structure, a particle generation unit 12 sets a maximum SPH particle diameter for which a pullout resistance force resulting from an analysis and indicating an undervalued time history result does not occur, and generates SPH particles modeling soil, which is a supporting body for the underground structure, and a computation unit 14 carries out an interaction analysis of the structure model and the SPH particles by means of a finite element method and a SPH method.
