WITHDRAWN The Use of the H/v Ratio for Back-Calculation of Normalized Shear Modulus G/g0

Description: 

WITHDRAWN The HVSR technique is a passive single-station method used to identify the fundamental resonant frequency of a site under specific conditions. The obtained fundamental resonance frequency can be analyzed using nonlinear regression relationships between bedrock depth and average shear wave velocity. The application of the HVSR method to case studies has greatly increased in recent years due to the simplicity and high cost-effectiveness of the required types of equipment.

In this study, the empirical HVSR method was performed by the use of earthquake records selected from the Turkey Strong Ground Motion Database. For a strong ground motion station with a bedrock depth of 30 meters, approximately 300 earthquake records from past events ranging in magnitudes from 3 to 7 were used for the strong ground motion based HVSR analysis. In this regard, this study aimed to estimate the normalized shear modulus curve of the soil profile underlying the selected station, based on the back-calculation of the average HVSR curves obtained as a result of the analyses.
