This study aims to reuse timber building materials pulled down from an old existing house for earthquake-resistant improvement. Totally seven specimens, composed with four kinds of structural types, were used to subjected to static repeated load horizontally. The load carrying capacity, deformability, hysteretic energy absorption, and failure mode of the specimens were investigated. It is found that the specimens installed three sets of crossed short-diagonal members show the highest load-carrying capacity, those were about 2.0 of wall unit multiplier, which is equivalent to the wall with crossing braces of the same size cross-section. The hysteretic energy absorption quantities of these specimens were also large, comparing the other specimens. However, the members failed in splitting and brittle manner at the ultimate stage of loading, so there must be change in the failure mode.
