SEISMIC PERFORMANCE OF A MODEL REINFORCED CONCRETE BRIDGE PIER BEFORE AND AFTER RETROFIT

A series of experimental and analytical studies were performed on a 1/3 scale model pier before and after retrofit. The scale model represented a typical eastern U.S. nonseismically designed concrete bridge pier. The pre-retrofitted model pier was tested under quasi-static inelastic loading. A seismic retrofit philosophy, "capacity analysis and redesign", was introduced and implemented to retrofit the damaged model pier. The experimental behavior of the retrofitted model pier demonstrated that failure due to joint shear and bond/anchorage could be avoided. The model pier was evaluated before and after retrofit using the capacity/demand method and the equivalent lateral strength method advocated by the FHWA Retrofitting Manual for Highway Bridges.
