Experimental Study on the Confining Effects of Various Detailing Methods at Ends of Flexural Shear Walls

To develop the detailing methods at the ends of flexural shear walls. which are satisfying the ductility requirement corresponding to R = 3.5 and capable of improving the consturctibility, tests of ten isolated cantilever shear walls were carried out under the load condition comprising the cyclic lateral and constant vertical loads. major test parameters include the way of detailing and arrangement of transverse reinforcement in the boundary elements at the ends of walls, and placement of vertical reinforcement. From tests, comparable ductile behavior in test specimens incorporating the channel type of open hoops, compared with those incorporating the regular type of closed hoops, was observed.
