Obtaining Shear-Wave Velocity Structure from Broadband Seismic and Strong-Motion Recordings

摘要：

　　Horizontal-to-vertical spectral ratio (HVSR) analysis and inversion were applied to S-waves from a large database of broadband seismic and strong-motion recordings.The S-wave HVSR, in comparison with ambient noise spectral ratio, contains much information on the shear-wave velocity structure.In other words, inversion of S-wave HVSR provides a detailed shear-wave velocity structure, which can be better used for nonlinear site-response analysis.The results showed that the HVSR of the S-wave can be used to improve or constrain the soil shear-wave velocity profile obtained from other methods.
