Protective Measures in the Seismic Design and Retrofit of Long-Span Bridges

The use of protective measures in the seismic retrofit and/or design of six major U.S. bridges is described. The protective measures include the use of dampers for energy absorption and control of displacement; the use of isolation bearings for energy absorption and force-reduction; the use of ductile links for the control and localization of damage; and the use of stiffeners to prevent buckling and enhance ductility.
