Experiments on traditional wooden structures with devices to improve earthquake performance are performed. Devised points are as follows. 1) Kashira-nuki and Nageshi are improved and employed as structural elements. 2) Boards of wooden siding wall, in which are Chikara-nuki and Chikara-ita arranged by turns, is developed. Following things become to be clear as results. 1) The larger the column axial-force becomes to be, strength and stiffeness of Kashira-nuki increase. 2) Nageshi increases strength of structure by 1.5 times in the case with no Nageshi. 3) Wooden siding wall increases strength of structure by 3 times in the case without one.
