Abstract:In this paper, the effect of high-strength bars in web reinforcement is evaluated based on the test results in Japan. Discussions have centered on the effect on members' shear strength and reinforcement performance for splitting bond failure along longitudinal reinforcements. High-strength bars with a yield strength of 80,000 to 130,000 N/cm3 proved to be very effective in increasing the shear strength of members, especially for high-strength concrete. However, high-strength bars were no more effective than normal strength bars in preventing splitting bond failure. Formulas were derived for normal and high-strength bars to predict the ultimate shear force at shear failure as well as splitting bond failure in members.
