The aim of this paper is to show the results of the shaking table experimental study concerning the behaviour of the model of the timber-frame house under earthquake excitation and impact loading. In order to determine the basic dynamic properties of the undamaged structure, the free vibration and the sweep-sine tests were first conducted. Then, the model was excited using the time history record of the El Centro earthquake of 1940 and the free vibration and the sweep-sine tests were repeated. Finally, the structure was dropped form the height of 4.2 meters, so as to simulate the impact loading, and the change in the natural frequencies of the damaged structure was investigated. The results of the study indicate that the model of the timber-frame house survived the earthquake without any damage. On the other hand, considerable decrease in the natural frequencies was observed as the result of damage due to impact load imposed on the structure.
