The objective of this study is to repair three, half-scale RC bridge columns that will be tested to failure under slow cyclic loading. These columns will have fractured longitudinal and transverse steel. The ultimate goal is to develop repair methods for these columns using different techniques. In the first two columns, different Caltrans approved ultimate splices will be used, and in the third column, an enlarged section will be built in the plastic hinge area. The target performance for the repaired columns is to restore the lateral load and ductility capacity to the level that is comparable to that of the original columns.
Bridges designed with current seismic codes exhibit large displacement capacities, and the bridge total collapse is prevented. However, damage of duct...
The overarching goal of this study was to investigate the influence of repair to individual reinforced concrete bridge columns on the post-repair seis...
