Selection of Slide Member for the Shear Wall with Friction Damper

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.
