The effect of horizontal tied rebars concentrated in slabs instead of cotter rebars for precast reinforced concrete shear walls was studied. To investigate the seismic behaviour and the resisting mechanism to the lateral force, loading tests and FEM analytical studies were carried out for. Multi-story specimens which had different arrangements of rebars in the vertical joint between a cast-in-place column and a precast panel. Major conclusions are as follows: (1) The shear wall has a good deformation capacity and a strength if horizontal tied rebars are sufficiently arranged in slabs instead of cotter rebars. (2) It is necessary to reduce the capacity of wall reinforcements when the shear wall has horizontal tied rebars instead of cotter rebars. (3) It is able to pursue the experimental load-displacement curve by FEM analysis using bond elements which have stiffness in only one direction. (4) The resisting mechanism of the shear wall with sufficient horizontal tied rebars turns into the truss mechanism in each story.
