Abstract

During the last decades, the use of wood as construction material in multi-story buildings has increased in Europe. Compared to conventional concrete buildings, wood buildings are more sensitive to dynamic loading at low frequencies. Also, the response to dynamic loading is in general more difficult to predict for wood buildings, given a certain degree of accuracy. This is a consequence of the complex structure involving many joints between beams and plates as well as the variation in, for example, material properties of wood and in mechanical behavior of joints. In a previous study, the correlation between numerical simulations and measurement data of the dynamic properties of wooden building structures was investigated. It was found that the mode shapes and eigenfrequencies below 100 Hz were well correlated—that model is used as an example case in the present study. In this paper, we investigate the effect of variations in Young’s modulus of wood beams on the low-frequency vibration transmission, up to 200 Hz, in a floor structure due to harmonic excitation. By performing Monte Carlo simulations it was shown that the variations in Young’s modulus has a marked effect on the predicted vibration transmission. © 25th International Congress on Sound and Vibration 2018, ICSV 2018: Hiroshima Calling.
