Abstract
In this study, the breakout capacity of a single anchor specimen in concrete simulating the bridge bearing connection with the characteristics of reinforcement, anchor socket, bed concrete, and mortar was evaluated for shear. The concrete breakout capacities were compared based on the embedment length of the anchor socket and edge distance, and the difference between the existing design strength and the actual strength was determined, which indicated safety issues. In addition, the shear resistance performance of the effective anchor reinforcement was evaluated through the strain analysis of the reinforcement. Finally, Through the results of this study, a concrete breakout capacity formula that reflects the characteristics of the bridge bearing connection has been proposed.
