This paper addresses an analytical study on the maximum strength of the shear wall in which precast concrete wall panel is inserted, which is connected with the upper and lower beams using prestressing, and is not connected with the columns of the both sides. The load-deformation behaviors of wall panel and shear wall have been demonstrated through the numerical simulations using by the following slip model. The slip model for the joints of wall to beam is taken account of the actual phenomenon, which shows that the axial load changes in response to the lateral deformation of specimen. The analyzed results of the load-deformation behaviors show a good agreement with experimental ones, including the failure mode and the strength of the specimens, which are classified to three typical failure modes, slip failure at horizontal joint of wall panel to beam, flexural failure at the remained wall part around openings of wall panel and shear failure of wall panel
