Structural Details to Accommodate Seismic Movements of Highway Bridges and Retaining Walls
This report describes detailing for structural movements for bridges and retaining walls for new construction in the western and eastern U.S. Bridge retaining devices such as longitudinal joint restrainers, vertical motion restrainers, shear keys, and integral superstructure to substructure connections are described. Sacrificial elements, which include abutments and joints, are also described. An introduction to passive energy dissipating devices and isolation bearing systems is provided as well as recommendations for detailing. The minimum support length requirements are reviewed. The current practice for designing earth retaining systems for seismic displacements is reviewed and some recommendations for detailing are provided. The effects of substructure flexibility on the isolation system is documented. An example study and comparison is given to illustrate the impacts of substructure flexibility.
