A Study on Bond Strength for RC Column of re-bar and concrete by Reinforced with External Steel-Band
초록
영어
The purpose of this study is to evaluate structural capability. Specifically, the existing construction methods' inadequate achievements in constructability and reinforcement performance are improved and an experiment on axial load is performed with a reinforced concrete column test specimen constrained by steel bands. A total of 13 specimens were made, a bonding test was performed; and restraining effect by steel bands, bond failure mechanism between steel bar and concrete, the number of main reinforcements, concrete strength, concrete casting direction, and cross-sectional area of main reinforcement were considered. A compared evaluation of the findings of the study and the existing suggested formulas by researchers was performed, and a numerical analysis suggestion was proposed based on the result of the experiments.
