The objective of this study is to suggest a new type of reinforcing elements, Amida-shaped frame, for traditional wooden structures. First, to make clear the mechanical characteristics of Amida-shaped frames, we conduct the static loading tests of them. Next, we analyze the difference of the restoring force characteristics and the damages between frames in parameters, size and the number of horizontal members. Finally, we simulate the static loading tests with analysis models to confirm the mechanical characteristics which can't be identified at the experiments.
