Abstract:

This research evaluated the seismic behavior of bridges with longitudinal joints. The experimental portion of the work consisted of ten full scale sub-assembly tests modelled after a typical as-built keyway joint. The joint was tested under pure shear to determine the joint shear-slip response and associated limit states (grout cracking, embedded rebar yielding/rupture, and girder cover concrete cracking). The analytical portion consisted of developing inelastic shear springs between girders using the response from the experiments and implementing springs into superstructure models to determine global response. In addition, moment curvature analysis was done to develop equations for nominal yield curvature of bridge superstructures. An alternative keyway connection was proposed to improve performance at the service limit state.
