IDENTIFICATION OF DAMPING FACTOR CONSIDERING ITS LOWER LIMIT BY SPECTRAL RATIO INVERSION : Application to borehole array records at hard rock sites and evaluation of attenuation characteristics

A spectral inversion method adopting new functional model of damping factor with its lower limit is proposed for identifying more sophisticated attenuation characteristics of rock sites. The proposed model is applied to borehole array data recorded at hard rock sites. The identified lower limits of...
