为了确认在木结构房屋的使用期间由中等地震引起的反复小变形如何影响抗剪墙，使用胶合板、石膏板和木支撑进行了具有许多小变形的墙的面内剪切实验。即使在较小的变形下，胶合板和石膏板墙的荷载也会降低，等效刚度也会降低，因为重复相同的变形。在1/450 rad的重复200次时，胶合板墙的载荷下降至约85%，石膏板墙的载荷下降至约70%。石膏板墙体反复变形引起的荷载折减大于其它墙体。然而，特征值没有受到显着影响，即使墙收到重复的小变形。
To confirm how repeated small deformations caused by moderate earthquakes during the use period of a wooden house affect the shear resisting wall, in-plane shear experiments with numerous small deformations on walls using plywood, gypsum board, and wooden braces were conducted. Even with small deformations, it was found that the load decreased, and the equivalent stiffness decreased because of the repetition of the same deformation for plywood and gypsum board wall. At 200 times repetitions of 1/450 rad, the load decreased to about 85 % for the plywood wall and 70 % for the gypsum board wall. The load reduction due to repeated deformation of gypsum board wall was larger than that of other walls. However, the characteristic values were not significantly affected, even if the wall received repeated small deformations.
