REVOLUTION IN QUAKE DESIGN?

The California Department of Transportation (Caltrans) is using a method called displacement-ductility capacity analysis to retrofit a Los Angeles elevated freeway. This brief article describes the approach that involves quantifying in 5 to 20 increments how much a connection or member can deform or rotate without failing. Steel jackets on just 20 percent of the Santa Monica Freeway's columns are expected to accommodate potential displacements with reparable damage, saving Caltrans 30 to 40 percent of its retrofit cost. Use of the method in new construction should result in savings of 15 percent, based on less expensive foundations.
