Three concrete walls, whose longitudinal distributed bars were not anchored into adjacent beams, were fabricated and tested under cyclic lateral load to investigate the effectiveness of a new arrangement of longitudinal bars in wall panel as well as the influence of shear span ratio on seismic behaviors of the walls reinforced by SBPND rebars. The test results indicated that all walls exhibited drift-hardening behavior till drift ratio of 3%. Furthermore, an analytic method that can take account of the slippage of SBPDN rebars was presented to discuss the influence of arrangement of longitudinal bars. |
