Physical and Numerical Modeling of Dynamic Soil-Structure Interaction
A numerical model was developed to simulate the response of two instrumented, centrifuge model tests on soft clay. The centrifuge tests consist of a rigid containment to simulate the behavior of rectangular ten-storey buildings on 30 m uniform and layered soft soils. Each test model was subjected to several earthquake- like shaking events i.e. scaled versions of an artificial western Canada earthquake and the Port Island ground motion recorded during the 1995 Kobe Earthquake at a centrifugal acceleration level of 80g. The centrifuge model was simulated with the 3-D finite-difference-based Fast Lagrangian Analysis of Continua (FLAC) program. The results predicted with the use of nonlinear elastic—plastic models for the soil are shown to be in good agreement with measured acceleration, soil response, and structural behaviour. Numerical results were used to study the effect of soil layering and soil-structure interaction on foundation input motion.
