본 연구에서는 외부 보-기둥 접합부 반복가력 실험을 위하여 접합부 Hoop 근이 배근된 실험체와 배근되지 않은 실험체, 그리고 접합부 전단내력을 향상시키기 위한 2개의 실험체를 제작하였다. 이를 통해 접합부 Hoop 근의 유무와 X형 전단철근의 사용에 따른 접합부의 전단강도 및 내진 성능을 비교, 분석하여 접합부 상세에 따른 접합부 거동 특성을 파악하고자 한다. |

Current design philosophy permits moment-resisting frames subjected to seismic loading, apart from a few exceptions, to be induced into the inelastic range where the forces that develop in parts of the structure will exceed their design values. Therefore the joints need to dissipate large energy amounts. Paulay, Park, and Phillips first introduced the idea of using inclined main reinforcement to prevent brittle failure in short reinforced concrete coupling beams. Use of inclined reinforcing bars shows that achievement of high ductility behavior of structural elements is possible in several researches then. This study investigates the improvement in the seismic behavior of exterior reinforced concrete beam-column joints resulting from the presence of inclined reinforcing bars. Specially, to drive the joint brittle failure by the strength increase of beam that there is possibility to happen in general constructions, we designed the full-size specimens of weak-column / strong-beam. The test results show by inclined reinforcing bars that the strength, stiffness, and energy dissipation capacity were improved. But, more studies are required for achievement of high ductility behavior. |
