Research Brief
Description:

This research proposes a system of corrosion-resistant columns built with accelerated bridge construction using grouted ducts with ultra-high-performance grout, glass fiber reinforced polymer bars and spirals, and post-tensioning steel rods to reduce residual displacements after an earthquake. In the research, two hybrid precast concrete columns were investigated to assess their seismic performance using conventional steel and glass fiber reinforced polymer (GFRP) reinforcement. GFRP longitudinal bars and double GFRP spirals provide corrosion resistance and partial self-centering under cyclic loading. Two additional post-tensioned columns were investigated; post-tensioning was achieved using all-threaded prestressing bars to improve self-centering effectiveness using the same reinforcement as the first two specimens. All columns were connected to footings with corrugated galvanized ducts filled ultra-high-performance grout. The seismic performance of the four specimens was examined under quasi-static cyclic loads; all four specimens performed in a satisfactory manner with regard to strength and self-centering.
