STRUCTURAL PERFORMANCE OF PRECAST-CONCRETE JOINTS UTILIZING NON-WELDED SPLICE IN PRECAST-WALL RC STRUCTURES
In the precast-wall RC structures, the cotter-bars installed in the joints have been flare-welded. However, in terms of the assurance of the quality at construction cite, non-welding method is preferable for the connection of cotter-bars. In this research, in order to develop non-welding method, sta...

| description | In the precast-wall RC structures, the cotter-bars installed in the joints have been flare-welded. However, in terms of the assurance of the quality at construction cite, non-welding method is preferable for the connection of cotter-bars. In this research, in order to develop non-welding method, static loading tests are carried out for the total of 17 specimens with I-, T-, L-shaped vertical and horizontal joints utilizing clip-type splices as well as flare-welding. Each specimen has practical configuration of shear-cotters. Major findings include: (1) vertical joints utilizing clip-type splices exhibit the ultimate strength similar to those utilizing flare-welding, and (2) T- and L-shaped vertical joints exhibit approximately 0.8 times ultimate strength of I-shaped vertical joints due to the inclination of the angles of concrete compression struts developed in in-plane and out-of-plane walls. |
