概要	A building system consisted with “coupled shear core walls with damper”, CFT (Concrete Filled Steel Tube) columns, and flat plate slabs is one of the buildings having an ability of such demand. As floor load should be supported even in the large deformation at the CFT column-flat plate connection, it is required to avoid punching shear failure. To evaluate the vertical load resistance capacity of the newly designed CFT column-flat plate connection, experimental studies were carried out. The vertical force resisting mechanism of the joint zone is investigated and calculation can be made with fairly good accuracy by regarding a region with a shear force resisting vertical member as a truss system and regarding a region without such a member as an arch system. Vertical strength also can be calculated conservatively as a lower value of a simplified punching shear strength formula conforming to the ACI standard and a flexural yield strength value.
