The motion-limiting devices can be used for reducing the maximum and residual displacements of the multi-span continuous bridges with inelastic elements such as isolation bearings and plastic hinges formed in piers. For the design of motion-limiting device, the nonlinear time history analysis is required. But the time history analysis is time consuming and very complex. This study suggests the simple design procedure of the motion-limiting devices using the equivalent elastic analysis method and the acceleration-displacement spectrum concept. The suggested design procedure can be used very effectively for determining the location and gap size of the motion-limiting devices.
