Experimentally supported modelling of an existing masonry building by measuring ambient and forced vibrations [Elektronski vir]Snoj, Jure, gradbenik ; Österreicher, Michael ; Dolšek, MatjažSeismic performance assessment of existing masonry buildings is affected by many uncertainties, which are difficult to evaluate, especially, if destructive tests of masonry are not available. In such ... cases, the effect of uncertainties can be reduced by the use of non-destructive experimental techniques. However, their efficiency is not well defined. Thus we performed measurement of ambient and forced vibrations on an old two-storey masonry building. We investigated if such experiments can contribute to greater accuracy of the results. Herein the experimental setup is briefly described. The estimated vibration periods based on the two types of measurement are compared and seismic performance of the building is assessed for the near-collapse limit state. We found that accuracy of the seismic performance assessment of the building can to some extent be improved if structural model is calibrated to the estimated vibration periods.Source: 15th World Conference on Earthquake Engineering [Elektronski vir] : 24 to 28 september 2012, Lisbon, Portugal (Str. 1-10)Type of material - conference contribution ; adult, seriousPublish date - 2012Language - englishCOBISS.SI-ID - 5988193
