Description

This paper illustrates the effect of non-structural components on the variation of dynamic properties of buildings in the elastic range using ambient vibration testing. A six-storey reinforced concrete building that forms part of the École de Technologie Supérieure campus was studied. Ambient vibration tests were conducted on this building during its construction and once finished. Measured records at different floor levels served to extract the natural frequencies, mode shapes and damping ratios of the building. Values obtained for the studied building, both at bare frame and finished phases were then compared. Calculated differences in the natural frequencies of the building range between 1.6 % and 21.7 %. Results highlight the importance of considering the contribution of non-structural components such as glass, facades and partition walls in the process of structural analysis and modeling of buildings.
