Assessment of Foundation Rocking Behavior in Reducing the Seismic Demand on Horizontally Curved Bridges
It is critical to find ways to mitigate earthquake damage in bridges. One of the ways that has been proposed to achieve this is to permit the foundations to rock. In order to investigate the system effects of rocking foundations, a two-fifth scale, three-span horizontally curved steel plate girder …
