Resumen

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 resilient and damage-free bridges fully operational immediately after an earthquake. A shake-table testing program was conducted to subject a 1/2.5 scale specimen to series of ground motions. The specimen tested represents one span of a 5-span bridge having BRBs connected to the abutment and the pier next to it. The testing program validated the effectiveness of the proposed concept and the ability of BRBs (and their connection details) to sustain multiple ground motions before failure.
