Abstract

Steel side blocks are set besides the seismically isolating bearings of a viaduct and are designed as a joint protector against the Level 1 earthquake. The authors suggested the CSB as rapture controllable steel side block with knock-off function and as a trigger to provide isolation effect not only in the direction of the bridge axis but also in the transverse direction against the Level 2 earthquake. In this study, the knock-off effect of the CSB in a vibration system consisting of bridge pier-rubber bearing-mass is investigated through shaking table test. Also the installation effect of the CSB is verified through seismic response analysis of a viaduct with isolating bearings.
