title = "Evaluation of Damping Ratio of Buildings Using Seismic Interferometry Method",
abstract = "Seismic interferometry method is applied to evaluate the internal attenuation of buildings regarding the building as the sedimentary layers of one-dimensional layered medium. The original wave field is reconstructed to be a new wave field expressed by deconvolved waves with virtual source at the top, consisting single up-going wave and single down-going wave reflected at the top. The damping ratio is evaluated from the transfer functions of up-going and down-going waves of the deconvolved wave at the 1st-floor of a building. The feasibility of this method is investigated using a homogeneous model, a 2-layer model, and a heterogeneous model, imaging 10 story buildings. We found that the damping ratios of those models extracted from the transfer functions were consistent with the preset values.",
