Abstract
본 연구의 목적은 직접전단응력 및 휨 전단응력의 비교분석을 통하여 Perfobond Rib 전단연결재를 사용한 구조물의 하중방향에 따른 전단응력 분석이다. 직접전단응력 분석을 위해서 5개의 변수로 Perfobond Rib 전단연결재 실험체 5개를 제작하고 Push-out Test를 실시하였다. 실험 후 Perfobond Rib 전단연결재의 전단저항 메커니즘을 규명하고, 직접전단응력에 영향을 미치는 주요 인자를 바탕으로 직접전단력을 산출할 수 있는 제안식을 제시하였다. 또한 휨 전단응력의 분석을 위해 강-콘크리트 합성 바닥판 실험체를 제작하고 정적 휨실험을 실시하였다. 정적 휨실험을 바탕으로 휨 거동특성을 분석하고 휨 전단응력을 계산하였다. 직접전단응력과 EN 1994-1-1을 통해 계산된 휨 전단응력을 비교하여 하중방향에 따른 전단저항응력에 대해서 분석을 하였다. The objective of this study which it sees direct shear stress and comparative analysis of flexural shear stress leads and it is a shear stress analysis which it follows in load direction of the structure which uses Perfobond Rib shear connectors. To analyze direct shear stress, five Perfobond Rib shear connect experiments were fabricated with five variables and conducted Push-out Tests. After experiments, mechanism of Perfobond Rib shear connector was examined and direct shear formula was proposed based on primary factors which influence direct shear stress. Also, for the analysis of flexural shear steel-concrete composite slab specimens were fabricated and static flexural test. Based on the static flexural test it analyzed the flexural behavior and the flexural shear stress it calculated. Direct shear stress and EN 1994-1-1 to lead and be calculated, it compared the flexural shear stress and it analyzed in about the shear resistance stress which it follows in load direction.
