THE EFFECTS OF SIMULATED TRAFFIC VIBRATIONS ON A DWELLING HOUSE

This report describes an experiment to investigate damage caused to buildings by traffic-induced vibrations. A vacant property founded on loose to medium dense sand was located and subjected to separately generated groundborne and airborne vibrations, designed to simulate the effects of heavy traffic. Groundborne vibrations were simulated using a geophysical vibrator, airborne vibrations with a loudspeaker system connected to a microcomputer. The dynamic response of the structure was monitored using a computer controlled data collection and analysis system. Throughout the period of the experiment the condition of the structure, movements within the structure and movements within the underlying soil were monitored, using a range of precise measuring techniques. In order to widen the scope of the study, six sections of foundation strip were constructed close to the test house. These were subjected to various static loads and amplitudes of vibration. The behaviour of the strips was also monitored throughout the experiment. The report describes the experimental work and results in detail. Possible damage mechanisms are postulated and dicussed in the context of the very small amounts of movement and damage actually recorded. The distinction is made between the effects of airborne and groundborne vibrations. Conclusions are drawn regarding the overall risks of damage from traffic vibrations and circumstances which increase this risk are highlighted.
