본 연구에서는 콘크리트충전 각형강관 기둥-보 핀접합부에 대하여 유한요소해석 프로그램을 이용하여 기둥의 폭과 두께 변화, 내부보강 유무에 의한 변수로 해석을 수행하여 모멘트 발생에 따른 콘크리트충전 각형강관 기둥의 구조특성을 규명하였다. 또한 실험을 통해 유한요소해석결과에 대한 신뢰성을 확보하였다. 최종적으로 항복선 이론을 적용하여 콘크리트충전 각형강관 기둥-보 핀접합부의 내력식을 추정하고 유한요소해석 결과와 비교 분석하였다. |

The higher a building, the more concrete-filled square hollow tubular section column?beam connections are applied. The RC core and exterior concrete-filled tubular (CFT) column?beam pinned connection is one of the structural systems that support lateral load. If this structural system is used, due to the minimal CFT column thickness compared to that of the CFT column width, the eccentric distance of the column flange surface and connection degrades the strength by the local moment on the column flange surface. This study performed a finite element analysis on the CFT column?beam pinned connection to determine the strength degradation of the CFT column. The column’s width and thickness were used as variables for the analysis. To guarantee the reliability of the finite element analysis, an actual-size specimen was fabricated and tested. The yield line theory was applied in the proposed strength formula for the CFT column?beam pinned connection. Based on the study’s results, the strength improved with the increase in the column’s size, which suggested the limitations of the concrete-filled square tubular column type without internal reinforcement. If the limitation value is not satisfied, the reinforcement inside the column is mandatory. The form of the horizontal stiffener was proposed along with the strength increase of the concrete-filled square tubular column and simplification of its fabrication process. The formula for the strength of the CFT column?beam pinned connection, which factors the strength decline, is therefore proposed both for columns with and without internal horizontal reinforcement. |
