RC 부재의 전단거동에 미치는 축력의 영향에 대한 연구
Effect of Axial Force on Shear Behavior in Reinforced Concrete Beams
- 발행 : 2004.05.01
초록
It is well known that axial tension decreases the shear strength of RC beams without transverse reinforcement, and axial compression increases the shear resistance. What is perhaps not very well understood is how much the shear capacity is influenced by axial load. RC beams without shear reinforcement subjected to large axial compression and shear may fail in a very brittle manner at the instance of first diagonal cracking. As a result, a conservative approach should be used for such members. According to the ACI Code, the concrete contribution is calculated by effect of axial force and the vertical force in the stirrups calculated by
