New Sesimic-Resisting Connections for Concrete-Filled Tube Components In High-Speed Rail Systems

The overall goals of the proposed research are to investigate CFT connections and other column-to-pile connections including the seismic response and resilience, including damage, of selected CFT connections using high-resolution finite element analyses. Longer term work (beyond Cycle 1) will focus on investigation of a high-speed rail (HSR) system for study (to be selected in collaboration with the CA HSR technical team) through a limited structural analysis simulation using line-element nonlinear modeling methods to investigate the impact of salient parameters on the response including (1) connection type, (2) soil structure interaction and (3) seismic hazard level.
