The present paper proposes the retrofit use of dynamic restrainers at the expansion joint for preventing the collapse of bridges in the event of a severe earthquake. The proposed dynamic restrainer consists of a nonlinear viscous damper and an elastic spring connected in parallel. Two-dimensional nonlinear finite element analysis using bilinear hysteretic models for RC bridge substructure joints and nonlinear gap elements for expansion joints is performed on example bridges with one or two… CONTINUE READING
