Prediction of Shear Strength of Reinforced Concrete Members with High-Strength Materials using Truss Models

트러스 모델에 의한 고강도 재료가 사용된 철근콘크리트 부재의 전단강도 예측

This study is to propose a truss model which is able to reasonably predict the shear strength of reinforced concrete (RC) members with high-strength materials. The shear strengths of 107 RC test beams with high-strength steel bars reported in the technical literatures were compared to those obtained from proposed model, TATM, and existing truss models. The shear strength of reinforced concrete beams obtained from test was better predicted by TATM than other truss models. Also, the theoretical results by TATM were almost constant regardless of yield strengths and steel ratios of tension and shear reinforcements.
