Abstract

We numerically simulated a shear loading test of a shear key, and evaluated the mechanical behavior of the shear key with rolling and plastic deformation. We considered that the load-displacement relationship was influenced by contact condition of the key and the upper key plate, and compared the load-displacement relationship with rolling and deformation of the shear key. The horizontal load increased until the edge of key lifted the upper key plate. After the edge of key lifted the upper key plate, the gradient of load-displacement curve became small and the horizontal load became almost constant. Next, we conducted simulation with different condition of vertical load, and investigated the influence on horizontal load. The result of investigation showed the tendency that the maximum horizontal load became larger as the vertical load became larger. This result showed that the maximum horizontal load, nearly equal to the load of horizontal actuator necessary to lift upper key, seemed to be decided by the vertical load.
