14. Experiments in the Vibration and Destruction of a Wooden Dwelling House

The author, in this paper, briefly describes the experiments that were made in connexion with the vibration and destruction of a wooden dwelling house. From observations of small vibrations due to slight earthquake shocks, the author has frequently pointed out that the vibration periods of wooden houses are proportional to their amplitudes. From this experiment, with artificial violent shakings, the author concludes that the vibration period of a wooden dwelling house is nearly proportional to its amplitude
