Laminated rubber bearing with small shape factor is regarded as one of the most promising isolation device to reduce the vertical seismic load of nuclear power plant. In this study,three types of natural rubber bearings with different aspect ratio(diameter/total thickness of rubber) and one high damping rubber bearing are tested under varied loading conditions. Basic characteristics and ultimate characteristics of the bearings are made clear, and applicability of estimation formula and analysis method are verified. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
