Abstract

Vibration measurements were recorded at three sites using a Bruel & Kjaer Frequency Analyzer. Some vibration signals were also tape recorded for Fast Fourier Transform (FFT) analysis. Diesel pile-driving vibrations, which reached a maximum of 0.036 mm/s Peak Particle Velocity at a distance of 15 metres from the Cleary Auditorium, and 0.176 mm/s at a distance of 25 metres from the Baby House, were not considered large enough to cause damage to either building. However, vibratory compacting recorded at the Bellewood Estates subdivision reached a maximum Linear RMS Velocity of 14.1 mm/s at a distance of 44 metres, and was considered to be of sufficient amplitude to cause possible damage to several nearby houses. The natural frequencies and damping of the Baby House were also determined through FFT analysis of the tape recorded vibration signal. Spectral Response analysis was found to predict vibration values of about the same magnitude as the other vibration prediction techniques explored in this thesis. However, each technique was found to be quite conservative, and over-predicted the vibration response by several orders of magnitude. Nevertheless, the Spectral Response method did have the advantage of being able to predict the frequencies of highest and lowest amplitude response.
