SEISMIC STRENGTHENING OF AN HISTORIC ARCH BRIDGE

This paper describes the recently completed seismic evaluation and retrofit project of the historic Russian Gulch Bridge, which carries California's scenic coastal Highway 1 over Russian Gulch State Park. Analysis showed that the existing bridge lacked an adequate lateral load carrying system capable of resisting the maximum credible earthquake. The retrofit strategy concentrated on measures that create alternative paths for the seismic loads, thereby minimizing the load demands on the arch and on other vulnerable parts of the system not designed to resist seismic loads.
