A horizontal loading test to the wooden framed wall using short diagonal members was carried
out. The test specimens were made of three sets of crossed diagonal members, in order to use
earthquake-resistant improvement of the existing houses. The diagonal members bear only
compression force and are expected to perform axial ductility. Two test specimens, each having a
distance between column centers of 910 mm (1P) and 1,820 mm (2P), were prepared, and the load
capacities were examined for difference due to the distance. The load at the specific deformation
of 1/120rad story-drift in elastic region and the ultimate load considering plastic region are
comparable, consequently the wall gives good performance in earthquake resistant improvement.
The wall load-magnification was 2.22 and 2.03 for the 1P and 2P specimens, respectively. The
partial breakage of tie-plates at the middle crossing members led to load drop, when the story-drift
angle exceeded 1/50 rad.
