The precast concrete structure has been adopted in a lot of buildings up to now, and it is very useful for the economy and the quality securing. However, the execution method can still be improved. Then, this research proposes the precast wall including slits where the vertical joint was omitted. This paper experiments on three story frame, and compares the experiment result with the analytical result. And, six story frames is analyzed for practical use. The energy-absorbing capacity of the specimen of 1/1-0.84, 2/2-0.84, and 3/3-0.84 is almost more equal to the shear wall from the experimental result. The elasto-plastic analysis result of the specimen was corresponding to the experiment result of the precast wall until dividing into two. When the vertical joint bar was properly arranged, the analytical result of six story frame that modeled an actual building was a superior performance in ductility. However, it is necessary to take care about a decrease in the rigidity and an increase in the deformation in the design.
