Abstract: This paper describes a lens-type shear panel damper newly developed for highway bridge bearing. It has the form of concave lens shape made of low-yield steel LY 100. Both low yield strength and high ductility are the major requirements for damping devices. Response by static and dynamic shear tests results in rectangular sharpe of load-displacement hysteretic loops with high quality damping. Failure at the ultimate state highly depends on the cumulative deformation capacity of panel. Damage and life cycles can be estimated by Miner's rule. The analytical estimates agree well with the test findings. Large deformation of steel with high speed strain rate generates a lot of heat leading to high temperature of 300~400 ℃ on swface. Earthquake energy is converted to both strain and heate nergies wof hich results in large energy dissipation.
