CONTRIBUTIONS OF PLYWOOD SHEAR WALLS AND PLASTERBOADS ON SEISMIC RESPONSE REDUCTION OF TIMBER STRUCTURES USING WOOD FRICTION-BASED DAMPERS

Abstract

The study deals with the damage control system of wooden houses using wood friction-based dampers subjected to earthquake motion. In this study, wood friction joints were developed to introduce damping into wood shear walls. Shaking table tests were also conducted to investigate the seismic performance of two-story timber structures composed of plywood shear walls, plasterboards and timber shear walls using high damping devices. The purpose of this study is to propose an estimation method of the required quantity of the friction damper to satisfy the restriction value of the story drift angle for the continued use after earthquake motion.
