A large number of steel truss bridges were constructed in the U.S. when seismic resistance was not considered. Recent structural analyses of these bridges have revealed that they will likely suffer significant seismic damage and have a risk of collapse during their remaining service life. Contributing significantly to their poor seismic behavior is the built-up, lattice type members used to resist the lateral seismic forces and the pier anchorage connections resulting in very little effective system ductility. Also, these types of bridges may be a vital geographical link to a region and must remain operational following a major earthquake. Therefore, seismic retrofit strategies that enhance the global structural ductility, limit maximum forces transmitted to existing members and the foundation (capacity protect), and prevent residual deformations are needed.MCEER-05-001 0 aquot;Steel Plate Shear Walls for Seismic Design and Retrofit of Building Structures, aquot; by D.
