Characteristic Tests of Reduced-Scale High Damping and Lead Rubber Bearings

축소규모 고감쇠 및 납삽입형 면진베어링에 대한 특성시험고찰

The characteristic tests of reduced-scale high damping and lead rubber bearings are performed by changing the shear displacements and the vertical loads. The test frequency is 0.5Hz. Test results show that the shear stiffnesses obtained for both bearings are less than target values, but the damping values are greater than the targets. The shear stiffness and damping of lead are larger than those of high damping bearings. The shear-deformation characteristic values such as stiffness, damping and yield load values are changed according to the level of design vertical loads.
