Peudo Static Test Research for Seismic Shear Keys of Bridge

Abstract:

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.
