Adaptive camber precast concrete girder for deflection mitigation of highway bridges

The vision of this work is that through innovative use of expanding mechanical anchors, precast concrete bridge girders can adaptively camber to have zero deflection when subjected to external loads. Motivation for this work is twofold: topology optimization and long-term deflection control for transforming precast concrete research. This work will lead to cross-cutting research between concrete materials, structural design, architecture, and mechanical engineering. Work will begin on specimens intended for pedestrian bridges and will expand to highway and rail bridges in future projects.
