S-type and Horizontal Loading type experiments on Vertical Joint of Box-Frame-Type Precast Rrinforced Concrete were carried out. As a result, the followings were found. The strengths at which shear crack are produced have something to do with shearing area ratio, ΣA_2/A_1, and little to do with cotter bars ratio, P_s=Σa_t/A_1 P'_s=Σa_t/A_1 P'_s=Σa_t/ΣA_2. τ_<cr>/_jF_t=1.0・ΣA_2/A_1 gives a rough average, (in which,ΣA_2/A_1<0.6) Ultimate bearing strengths have something to do with shearing area and cotter bars ratio. But an ascent of bearing strenghs are not recognized very much at ΣA_2/A_1>0.6. Ultimate bearing strengths of Horizontal Loading type experiments took a figure when the quantity of slip of the wall panel through Vertical Joint amounted to 3 mm. But, yet this figure was very high in comparison with one of S-type experiments. Theretore, we are going to reconsiden in vext report.
