The bridge restrainers are expected to prevent unseating of bridge deck and also to resist the seismic impact force. However, standard evaluation and design method for the shock absorbers are not yet established. In the meantime, a pin fixed cable type restrainers are newly developed. The pin fixed assembly allows the cable to rotate, creating no restriction to their brackets' mounting angle. The purpose of this research is to understand the shock absorbing capacity of the new restrainers with rubbers around the pins. First, seismic force acting on the restrainer is estimated by the FE analyses on the bridge model, and then impact load tests are conducted to quantitatively evaluate the shock absorbing capacity of three different sizes of the bracket models of the new type cable restrainers.
