Abstract
An earthquake resistant structure for mounting on a base having a limited available surface has an upper bearing and a lower bearing compactly arranged, one with a convex surface and the other with a concave surface, in contact with each other to transmit load between a bridge and a supporting pier, for example, the bearings being slidable relative to each other; a pin is provided for fixing the upper and lower bearings and an extraction preventing member prevents the bearings from separating from each other; a seal member is disposed between the upper bearing and the lower bearing; and a dust prevention and anti-corrosion cover are provided to assure long-time use.
