一般注記This paper describes a lens-type shear panel damper newly developed for highway bridge bearing. l), 2), 3) It utilizes low yield steel LY100 and concave lens shape. Both low yield strength and high ductility are the major requirements for damping devices. Both responses by static and dynamic shear tests result in rectangular shape of load-displacement hysteretic loops with high quality damping. The failure at ultimate state highly depends on the cumulative deformation capacity of panel identity. Damage and life cycles can be estimated by Miner's rule. Prediction matches well with the testing results. Large deformation of steel with high speed strain rate generates a lot of heat leading to high temperature of 300~400℃ at surface. Earthquake energy is converted to both strain and heat energies,which results in large energy dissipation.
