Self compacting hybrid fiber reinforced concrete composites for bridge columns

The study developed a self-compacting hybrid fiber reinforced concrete (SC-HyFRC) composite. Optimized specifically for bridge columns, this composite flows under its own weight, completely filling the formwork and achieving full compaction without internal or external vibration. In addition, this SC-HyFRC provides enhanced ductility, shear resistance, and damage tolerance compared to conventional fiber-reinforced composites. To investigate the seismic performance and post-earthquake damage resistance of bridge columns composed of SC-HyFRC, two 1:4.5 scale column specimens were built and tested statically under uni-directional cyclic loading. In both specimens the volumetric transverse reinforcement was 0.37%, which is two to three times less than that of typical Caltrans bridge columns. Both specimens attained large drift ratios of up to 11% without losing axial load carrying capacity and were successful in resisting damage due to spalling of concrete up to drift ratios of 3.6%. Compared to a conventional reinforced concrete column of same dimensions, longitudinal steel ratio, and axial load ratio, the SC-HyFRC columns exhibited superior damage resistance and better load carrying capacity despite a 50% reduction in transverse reinforcement.
