This study aims to investigate load-deformation capacity of the walls including with three sets of crossed diagonal timber members under earthquake, in order to use earthquake-resistant improvement of the existing wooden houses. Two types of three braced wall specimens installed wooden frames, totally six specimens, were tested under repeated static loading horizontally, simulated earthquake load, in relative story-drift from 1/450 rad to 1/10 rad. The diagonal members like braces bear only compression force and are expected to perform axial ductility. It shows that relatively high earthquake resistance of the wall magnification (load carrying capacity), from 2.7 to 4.5, is obtained. The load at the specific deformation of 1/120rad story-drift in elastic region and the ultimate load capacity based on the structure properties coefficient Ds are comparable, consequently the wall gives the good balance in both elastic and plastic regions.
