[SSS26-P15] Application of deconvolution interferometry to extract quality factor of high-rise buildings
Keywords:Deconvolution interferometry, quality factor, microtremor, high-rise buildings
In this study, we focus on extracting the quality factor of shear waves from deconvolved waves with reference record on the ground floor. We conducted the microtremor measurement simultaneously in five floors for an hour by employing five sets of velocity seismometers with an 800 Hz record logger in several high-rise buildings being over 20 stories. The measurement is accomplished by moving four sets of equipment sequentially with one set fixed at the reference floor. The extracted quality factors of the buildings are expected to provide a reference for damping factor in the analysis of structural response.
