헤드 철근을 주근으로 사용한 철근콘크리트 깊은 보의 전단거동에 관한 연구

다국어 초록 (Multilingual Abstract)

In RC structures, standard hook is the effective anchorage method of the main longitudinal tension reinforcement. But, the use of standard hook results in steel congestion, so that the fabrication of steels would be difficult.<br/>
Headed reinforcement offers advantage in reducing the congestion of steels. The objective of this study is to investigate the shear behaviors of reinforced concrete deep beam with headed longitudinal reiniforcement. Ten deep beams are designed to study the anchorage capacity of headed reinforcement as well as the contribution of shear reinforcements and the effect of share span-to-overall depth ratio(a/h).<br/>
From the tests, it was shown that headed reinforcement could replace standard 90-degree anchorage as the anchorage method. Based on the test, shear design formulas of ACI 318-99 and AIJ Code were evaluated. The ACI 318-99 Code is shown to be conservative, while the AIJ Code are unconservative.
