Estimation of shear wave velocity of soil in vicinity of Tehran strong motion stations using inversion of H / V spectral ratio

The overall assessment of damage to structures and installations in an earthquake indicates that site conditions have a significant impact on the distribution of damages in towns and villages. In this study, the effect of soil layering on strong ground motion was investigated using accelerograms recorded at the Road, Housing and Development Research Center as well as Tehran Disaster Mitigation and Management Organization stations. Predominate frequency was estimated for each station based on Nakamora methods in order to identify the type of soil in the Tehran City. A good agreement was obtained between the results of this study with those obtained from experimental studies. Finally, the distribution of shear wave velocity from the surface to the depth of 30 m was presented in this study.
