EXPERIMENTAL STUDY ON DYNAMIC BEHAVIOR OF PASSIVELY-CONTROLLED WOODEN FRAME WITH OIL DAMPER USING POST-TENSION

Abstract

In passive control systems in wooden houses, the members and joints around the damper (: support member) tend to be deformed locally, which reduce the energy absorption of the damper. The authors have proposed the passive control system with post-tensioned and reinforced support members. In this paper, the effectiveness of the system is verified from the mechanical and dynamic characteristics and seismic behavior obtained through static and dynamic tests and shaking table tests. Also, the maximum response prediction method of the passively controlled wooden frame with oil dampers is proposed and predict the results of the shaking table tests.
