Pre-test System Analysis• Perform seismic simulations of bridge systemsunder combined actions to study effects of variousbridge components on global and local seismicresponse behavior of bridge system• Bridge superstructure• Columns (Piers)• Foundations and surrounding soil• Embankments• Nonlinear soil-foundationfoundation-structure interaction• Multi-directional motions
Analysis• Selected 4 ground motion suites that incorporate thesite-dependent probabilistic hazard analysis and groundmotion disaggregation analysis.• Selected 2 bridge prototypes that are distinctive interms of structural characteristics and dynamicproperties.• Conducted time history analysis of prototype bridgessubjected to multi-directional ground shakings andevaluate the effect of vertical motions on seismicdemand.• Implemented nonlinear structural and foundationelements.
