Precast prestressed concrete bridge piers are constructed by piling up bridge pier segments with embedded external steel pipes, installing internal steel pipes in external pipes so that internal steel pipes might penetrate segmental joints, and applying tensioning to prestressing steel and injecting grout.
In this study, a design model was proposed for the prestressed concrete bridge pier with internal steel pipes, and the seismic design method was examined. A scale model of a precast prestressed concrete bridge pier made by trial design was subjected to Level-2 seismic ground motions using a shaking table. The objective was to verify seismic performance of the model and the validity of the design method.
