Abstract

The restoring force characteristic of wooden houses is slip type. The energy absorption of slip type restoring force characteristic is less than the energy absorption of normal bi-linear characteristic restoring. On the other hand, a shear wall of wooden houses is evaluated with the resisting force ratio of various wooden walls. If a shear wall which has both normal bi-linear characteristic restoring and the high resisting force ratio of various wooden walls, that wall is valuable. In this paper, we develop a wooden wall which a steel frame and a friction dumper. We adopt aluminum, zinc or polycarbonate as slide mamber. As a result, the wall that we developed has the bi-linear restoring force characteristic, and the resisting force ratio of various wooden walls is 4.0. The bearing force deterioration of this wall is 0.1-0.2kN/cycle with aluminum as slide member.
