SEISMIC RETROFITTING CALIFORNIA'S LANDMARK: THE GOLDEN GATE BRIDGE

The Golden Gate Bridge is actually seven structure types: the North and South Steel truss approach viaducts, the Fort Point steel arch, the steel cable's concrete anchorages and concrete anchorage housings, the main span steel suspension bridge, and the art deco concrete pylons which are purely architectural motifs. All of the foundations for these structures, except the northern viaduct, are supported directly on rock. The seismic retrofit methods developed for the seven structural types comprising the Golden Gate crossing has shown that all seven can be structurally upgraded to meet the Performance Criteria, the Design Criteria and the Architectural Requirements developed for the project. With the new techniques, the functional reliability of the Golden Gate Bridge has been increased to an acceptable level for earthquakes likely to occur in California.
