Discrete Modeling of Soil-Structure Interaction Under Dynamic Loadingby Grzegorz Bak, Military Univ of Technology, Warsaw, Poland,
Abstract: A proposal of discrete modeling useful to describe behavior of structures burried in the ground under air explosion is presented. In the modeling emphasis is laid on determining the space and time distribution of loading transmitted from the adherent soil to the structure and reverse. A closed reinforced concrete frame is the exemplification of the structure. The frame sustains nonlinear vibrations and pushing down. An approximate one-dimensional model of dynamic response of the soil is assumed. Analysis of the frame is performed including dynamic straining material models and geometrical nonlinearity.
