Numerical Modeling and Simulations of A Complete Earthquake-Soil-Pile-Bridge Seismic Performance

Presented is the development of a complete Soil-Pile-Bridge (soil-foundation-structure, SFS) system model (three bents, four spans) in three dimensions subjected to seismic loading. In addition to that, presented also are illustrative and interesting results describing varying performance of the SFS system depending on the local soil conditions, beneath each bent. Seismic shaking results for varying soil conditions beneath bents indicate that local soil conditions (can) have significant effects on dynamics of SFS system. Among other findings, it is noted that free field motions are quite different from motions observed (simulated) at the base of bridge bents, hence SFS interaction plays significant role in dynamics of a SFS system. In addition to that, dynamic characteristics of earthquake also plays significant role in seismic response of SFS system. Presented work constitutes another step in our effort to develop high fidelity models and simulation tools for use in performance based design of infrastructure objects.
