Abstract

Understanding how regional geology and soil conditions affect the intensity of ground shaking is one of the fundamental tasks of seismology and earthquake engineering. As a result, it is necessary to explore a wide range of features, including material, nonlinearity, and different non-linear models. In this study, five different earthquake models with peak accelerations ranging from 0.01 to 0.8g are used to examine the impact of the local site on design parameters. This study uses three different types of recorded ground motions, with maximum accelerations between 0.001 and 0.1g (type I), 0.1 and 0.3g (type II), and 0.3 and 0.8g. (type III). Downhole tests in four bore-holes in the Hormozgan province were used to assess wave shear velocity (Vs) for this purpose. To determine soil parameters, various tests such as sieve or hydrometer and atterberg limits were performed on samples. The results showed that a larger frequency band is caused by increased soil cohesiveness and that the frequency band's increase enhances the possibility of resonance. Based on the results, it is clear that the non-linear method provides a more comprehensive explanation of true non-linearity in soil behavior than equivalent-linear approaches. This study tends to support the idea that site analysis is essential for significant projects and that response analysis should be performed on each identified site.
