Peudo Static Test Research for Seismic Shear Keys of Bridge
To investigate seismic performance of lateral bridge shear keys with different stirrup types, depths and impact degrees, tests in low frequency cyclic load have been done for 5 lateral shear keys. The results show that unbind stirrup shear key adopted is obviously weaker than bind one in terms of ductility ability; when bind one is adopted, it is mainly characterized by bending shear failure mode, its bearing capacity increases with depth. Finally a computational formula for seismic capacity of shear keys is presented according to its failure mechanism.
