AbstractIn this short note, we estimate the fundamental period of twelve reinforced concrete (RC) buildings in the cities of Victoria and Vancouver (British Columbia, Canada) using ambient vibration data. A preliminary height-dependent relationship to estimate the fundamental period of vibration for Canadian RC buildings is derived for a fully elastic condition. The results for Canadian buildings are very similar to those measurements of RC buildings in Europe. Both the Canadian and European results show that building periods estimated based on simple equations provided by earthquake design codes in Europe and North America (EC8, UBC97 and NBCC-2005) result values significantly greater than the periods computed using ambient vibration records.
