To clear the static and dynamic hysteresis characteristics of wood-framed residential structures, shaking table tests and static loading tests using various walls which composes wooden house, and full-scale shaking table test and static loading test on the same plan. Comparing the load-deformation relation of the full-scale tests, the dynamic test exceeded the static test in the load at the same deformation angle, and the dynamic test showed 119%-123% of the static test until 1/200rad on the 1st floor. The load-carrying capacity, which was estimated by summing of static hysteresis characteristics in walls, was checked with the result of the full-scale dynamic test. By summing all wall elements, which were thought as the surplus force, the stiffness was estimated in about 90% of precision until 1/75rad. but the maximum load and toughness weren't evaluated in the larger deformed range. As for the sharing rate of the horizontal-force of braces of the full-scale tests, it was about 20-50% in the static test and about 30-45% in the dynamic test. It's considered that the effect of wall elements except braces worked in the dynamic tests more than the static tests.
