Evaluation of Reinforcement Tension in RC Beams without stirrup using Truss Model

트러스 모델을 이용한 스터럽이 없는 철근콘크리트보의 주철근력 평가

This paper describes an evaluation of reinforcement tension in RC beams using the variable truss models. The models were examined with the beam test results by Kim, Kim and White. Consequently, a fixed inclination $\theta$ at the support un-explains global state of internal force flow in cracked reinforced concrete beams subjected to shear and bending. Accordingly, we must introduce the arch factor for development of consistent model in reinforced concrete beams subjected to shear and bending
