In order to investigate the effect of eccentric characteristics of full scale two storied wooden houses, shaking table tests were carried out. The main results are as follows. The natural frequencies of these houses are scattered from 5.3 Hz to 5.9 Hz based on microtremors. Deformation shapes of these houses are nearly first mode in either case of microtremor and harmonic excitation. Increasing of a distance of static rigidity centers between upper and lower floor makes a increase of torsional angle between upper and lower floor in case of microtremor and harmonic excitations. Torsional oscillation of houses having diferent eccentricities on upper and lower floor influenced by a rigidity center of lower floor especially in case of harmonic excitations.
