Abstract |
This investigation deals with monotonic behavior for longitudinal reinforcement of reinforced concrete bridge piers. The purposes of this study are to verify currently used monotonic models and to propose a rational monotonic tension?compression model for longitudinal reinforcement of manufactured reinforcing steel in Korea. One hundred thirty-eight specimens of longitudinal reinforcement were tested under axial strain control. The tests were performed for test variables of yield strength and reinforcement bar size. Modified models of monotonic tension stress-strain and monotonic compression stress-strain were proposed on the basis of the monotonic tension and compression test results of longitudinal reinforcement.
