通过对胶合板、OSB、MDF和石膏板进行单面剪切试验，确定中地震引起的循环变形是否会影响木制房屋的抗剪力墙。结果发现，即使反复小变形，对最大载荷和屈服载荷的影响也不显著。由于反复变形，石膏板的减载率高于其他板材。重复试件的等效刚度也相应降低。认为剪力墙在反复变形时，其等效刚度减小。
A single face shear experiment with numerous small deformations of the nailed joint was performed on plywood, OSB, MDF, and gypsum board to confirm whether cyclic deformations caused by moderate earthquakes affect the shear resisting wall of a wooden house. As a result, it was found that the maximum load and yield load are not significantly affected even when repeatedly small deformed. The reduction ratio of the load of gypsum boards was higher than that of other boards due to repeated deformation. Additionally, the equivalent stiffness of repeated specimens was reduced accordingly. It was supposed that the equivalent stiffness of the shear resisting wall decreases when it is repeatedly deformed.
