고강도 콘크리트를 사용한 보-기둥 접합부의 비 선형 거동에 관한 기초적 연구

A Fundmental Study of the Inlastic Behavior of High Strength Concrete Beam-Column Joints.

Six small-scale reinforced concrete beam-column joint specimens subjected to monotonic and cyclic loading were tested to investigate the effects of strength of concrete. Variables are 1)compressive strength of concrete(f' c=300, 700kg/㎠), 2)shear span to depth ratio (a/d=4.7, 2.0). The major results of this test were: 1)flexural strength of high strength concrete beam-column joint was not affected too much by the compressive strength of concrete, 2) flexural cracks emerge to inside of beam deeply for high strength concrete member.
