| Research Abstract |
(1) The main results described in this study about the evaluation of torsional response based on vibration table test of three dimensional frames induced translational and diagonal direction are as follows. Torsional response induced by vibration of diagonal direction is larger than that of translational direction. Amplification coefficient of stress based on time-domain response analysis is larger than corrected torsional coefficient or shape coefficient based on static characteristics.
(2) The main results described in this study about the effect of arrangement and area of floor well to vibration characteristics of two storied wooden houses by means of vibration table tests are as follows. Specimens with floor well that situated at side of weak wall are apt to vibrate with large torsion. The relative displacements between first and second floor are apt to influenced by mass eccentricity, and those of second and third floor are apt to influenced by floor well .
