| Zusammenfassung |
| The aim of this study is to classify the site effect using
concentration–area (C–A) fractal model in Meybod city, central Iran, based
on microtremor data analysis. Log–log plots of the frequency, amplification
and vulnerability index (k−g) indicate a multifractal nature for the
parameters in the area. The results obtained from the C–A fractal modelling
reveal that proper soil types are located around the central city. The
results derived via the fractal modelling were utilized to improve the Nogoshi and
Igarashi (1970, 1971) classification results in the Meybod city. The resulting categories
are: (1) hard soil and weak rock with frequency of 6.2 to 8 Hz, (2) stiff
soil with frequency of about 4.9 to 6.2 Hz, (3) moderately soft soil with
the frequency of 2.4 to 4.9 Hz, and (4) soft soil with the frequency lower
than 2.4 Hz. |
