Abstract

Nonlinear elastic-plastic model of soil-structure interaction in time domain B. Wrana Structure Mechanics Institute, Civil Engineering Department, Technical University Krakow, ul. Warszawska 24, 31-155 Krakow, Poland SUMMARY A nonlinear soil-structure interaction model in a time domain is considered. Nonlinear effects are calculated from elastic-plastic CAP material model of soil adjoining the structure foundations. Non-reflecting boundary condition (NRBC) for simulation of unbounding far field are used for artificial boundary. Numerical method for solving local nonlinear equation of motion is defined. 1. Introduction. Linear analysis of soil-structure interaction for dynamic excitation is established for frequency domain [34] and for time domain [5,35] employing some kind of substructure techniques. Nonlinear analysis in time domain take into account nonlinear elastic-plastic material of soil [4,11] near the structu
