대형 콘크리트 판넬 구조의 수직접합부 전단내력 ( Shear Strength of Vertical Joints in Large Concrete Panel structures )

In large concrete panel structures, the design of joints which interconnect panels, is important to decide of the load-bearing capacity of structures. Being various factors in the design of joints, it is difficult to develop a theoretical system for the structural analysis of large concrete panel structures. Therefore there is a tendency to depend on the experiment. Experimental study was performed to investigate the strength and the mechanical behavior of vertical joint. For this, 20 specimens were tested with following parameters; (1)Joint type : A, B, C, D, E (2)Number of loop bar : 2, 3 (3)Location of loop bar : In or out place in shear key (4)Wall thickness : 14cm, 20cm.
