abstract = "The seismic performance of high type steel bridge bearings of both the fixed and expansion/rocker type are investigated. Simple seismic retrofit strategies are proposed and investigated experimentally. It is shown that by retrofitting existing high type steel bridge bearings it is possible to provide sufficient strength and displacement capability to withstand substantial ground shaking. The weak link in the chain of force transmission may thus become the anchor bolts and/or the reinforced concrete pedestal. In order to understand the influence of the reinforced concrete pedestal and mild steel anchorage on the overall behavior of a high type fixed bearing assembly, a full scale reinforced concrete cap beam with pedestals was constructed. The test results demonstrate the importance of considering the flexibility and strength of the concrete pedestal-anchor bolt system. As a retrofit method for the damaged reinforced concrete pedestal a steel jacketing retrofit wrapped around the damaged reinforced concrete pedestal and bearing was investigated. Once retrofitted, it is shown that essentially elastic behavior may be expected in an earthquake.",
