Design and characteristics of high damping natural rubber bearings for base isolation K.A. Malek & K.B. Basir Technology and Engineering Division Malaysian Rubber Board, Malaysia Abstract High damping natural rubber bearings are effective in providing protection to structures from damaging effects of an earthquake. There are many buildings around the world which are mounted on rubber bearings and these buildings as expected were not damaged during the recent Kobe and Northridge earthquakes in 1995 and 1994 respectively. Although the Peninsular Malaysia is generally considered as seismically stable, the state of Sabah in the eastern part of Malaysia is not. Recently a 3-story reinforced concrete frame building mounted on high damping natural rubber bearings was constructed in Sabah. This paper describes the design of the isolation system and the individual bearings. The properties of the rubber and the bearings are presented. 1 Introduction To many structural engineers, the co
