In this study, I carry out following three series of experiments: series A: hanging walls with horizontal slit at the bottom of the beam, series B: mud walls with horizontal slits at the top and the bottom of the wall and walls without beam and series C: mud walls with various opening. The following findings were clarified from the experiments: If the story deformation angle is 1/30 rad or less, the presence or absence of slit of the hanging wall would be irrelevant to the stiffness and strength. When there are the slits on the top and bottom of the wall, both the stiffness and strength would decrease by 0.75 times compared to when there is not slit.
