A series of comparative static and dynamic tests on three types of concrete shear keys has been completed. Results indicate that plain concrete shear keys can withstand stresses as high as 2000 psi , that imposing transverse compression on the keys raises the ratio of shear to compressive strength by about 50 percent in the dynamic loading case though by only about 5 percent in the static loading case, and that keys indicate much higher shear strengths when loaded dynamically than statically.
