Testing of frequencies identification techniques on a reinforced concrete building FE model

Testing of frequencies identification techniques on a reinforced concrete building FE model In the last years, non-destructive techniques based on ambient vibration data have been developed in order to estimate the modal parameters (natural frequencies and mode shapes) of buildings. They have been performed mainly by using the accelerometers data of slender buildings. The present paper illustrates an assessment of identification techniques, applied to the numerical results of a finite element (FE) model obtained for a reinforced concrete frame building. The frame, with a four storey configuration, has been designed in accordance with the actual Italian seismic guidelines which respect the provisions of the Eurocodes. Several tests have been conducted in order to determine a suitable procedure that can permit to identify, from the data of virtual accelerometers placed on the building model, the relevant correct modal parameters. This procedure may permit to identify the correct number of accelerometers and their position within the structure, in order to guarantee a good frequency identification in real conditions in terms of external excitement. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Structural Engineering Inderscience Publishers

Abstract

In the last years, non-destructive techniques based on ambient vibration data have been developed in order to estimate the modal parameters (natural frequencies and mode shapes) of buildings. They have been performed mainly by using the accelerometers data of slender buildings. The present paper illustrates an assessment of identification techniques, applied to the numerical results of a finite element (FE) model obtained for a reinforced concrete frame building. The frame, with a four storey configuration, has been designed in accordance with the actual Italian seismic guidelines which respect the provisions of the Eurocodes. Several tests have been conducted in order to determine a suitable procedure that can permit to identify, from the data of virtual accelerometers placed on the building model, the relevant correct modal parameters. This procedure may permit to identify the correct number of accelerometers and their position within the structure, in order to guarantee a good frequency identification in real conditions in terms of external excitement.
