In order to obtain the amplitude dependency of dynamic characteristics of a two storied contemporary timber house, vibration table tests were carried out. The main results are shown below. Natural frequency of the house becomes small as the vibration force becomes large. Contraraly, damping coefficient becomes large as the vibration force becomes large. Torsional angle between first and second floor becomes large as the vibration force becomes large, and this angle is larger than that between second and third floor.
