Many studies have been conducted on energy dissipation walls for small houses to improve the earthquake resistance of structures in Japan. Oil dampers, a main damper, is installed in studs to increase their strength. However, this method tends to deform each member and joint-"support members"-owing to tensile force, and therefore, the energy absorption performance of the damper tends to decrease. In this study, we propose an energy-dissipation wall that increases the overall stiffness by prestressing the support members to prevent tensile deformation. From 2020 to 2021, two types of specimens using laminated veneer lumber (LVL) as supporting members-Type 1 and Type 2-were tested to understand the mechanical behavior of the wall. Both types were subjected to static loading tests. Additionally, dynamic loading tests were applied to Type 2. Moreover, the dynamic behavior of the one-story wooden structure installed on the Type 1 wall was investigated by subjecting it to artificial earthquake waves. In state R which the damper part of the energy dissipation wall is restrained the load-deformation relationships obtained from the static loading tests for the two types of specimens using LVL as support members showed almost linear behavior up to the assumed damper load level for both specimens. In the dynamic loading test on Type 2, a stable load-deformation history with almost no slip was obtained. In shaking table test on Type 1, it was found that the energy dissipation wall incorporated into the wooden structure absorbed the energy of the artificial earthquake shaking and prevented the deterioration of its bearing capacity.
