Experimental Evaluation of Seismic Performance for Seismic Isolation Bearings
지진격리장치의 내진성능에 관한 실험적 평가
- Published : 2010.06.10
Abstract
Experimental studies for the high damping rubber bearing, lead rubber bearing and natural rubber bearing, those are often used to improve the seismic capacity if the structure recently, are conducted to evaluate the seismic capacity of the seismic isolation bearings. The shear stiffness of the bearings decrease and the shear strain amplitude or the constant axial load level increase, but not sensitive to the strain rate effect. Bearings are strong for the axial compression but weak for the axial tension.
