ABSTRACT ,),JY ,.,1_/_.' . ' ' ' High damping 'la,rnmat'ea e 1 t_ as omenc b earmgs are becoming the preferred device for'ilsot_ting large buildings and structures, such as nuclear power plants. The key component of these bearings is a fillednatural rubber elastomer. This material exhibits nonlinear behavior within the normal design range. The material damping cannot be classified as either viscous or hysteritic, but it seems to fall...
