초록
본 연구에서는 고강도철근콘크리트 보-기둥 접합부의 고성능화 기술 즉 콘크리트의 고강도화, 접합부 영역의 손상을 최소화하고 보의 소성힌지를 보의 내측으로 완전히 이동함과 동시에 내진성능을 향상시키는 고성능 설계상세 기술 및 고인성섬유 복합모르타르을 도입한 시험체를 제작하고 실험을 수행하여 이력거동을 평가하였다.
In this dissertation, experimental research was carried out to study the hysteretic behavior of reinforced high-strength concrete beam-column joints designed by high performance techniques, such as application of high-strength concrete, reducing of joint regions damage, moving of beam plastic hinge, advanced reinforcing detailings and High Ductile Fiber-Reinforced Mortar.(HDFRM) Specimens(HJCI), designed by the development of earthquake-resistant performance, moving of beam plastic hinge, and new design approach, were attained the moving of beam plastic hinge and developed significantly earthquake-resistant performance of such joints. Specimens(HJRP), designed with HDFRM, were indicated more stable hysteresis behavior, high load carrying capacity, and distributed crack pattern of specimens HJRP when compared to the control specimen.
