Issues Related to the Rapid Seismic Repair of Concrete Bridge Columns
Abstract Presented in this paper is research aimed at challenging the assumption that severely damaged reinforced concrete bridge columns are not easily repaired. An experimental program was conducted in which six large-scale bridge columns exhibiting buckled and fractured reinforcement were repaired using plastic hinge relocation and conventional materials. Discussion of several repair methods is presented along with the introduction of a simplified analytical approach by which the repair can be designed, and repaired member performance obtained. In addition, the implications of the availability of such a repair method on the limits of residual drift in a damaged system are explored.
