The Case of Strengthening the Base of a Deformed Retaining Wall

The vertical component of ground motions is known to cause severe damages certain structures. Long span cable-stayed bridges are among those vulnerable structures due their high mass and cables that take no compression. In this paper, the earthquake effects on several have been investigated using 3-D nonlinear time history finite element analyses. Different main lengths, pylon shapes pylon/deck connection types considered. results indicates motion should be considered in analysis such affects many key elements bridge.
