Abstract: The bidirectional ductile end diaphragm concept uses energy-dissipating buckling restrained braces (BRB) as fuses located at the end of a bridge superstructure’s floating spans. This system using BRBs can provide seismic ...

Abstract: Bridge design specifications include design provisions for ductile diaphragms to resist seismic excitations perpendicular to a bridge’s axis. Buckling restrained braces (BRBs) can conveniently be used for this purpose. ...
