Resumen

The site response analyzes provide an idea of the behavior of the soil against strong ground motions, involving a large number of variables that determine the non-linear behavior of the soil. Due to the complexity of these analyzes, in practice the effects of nonlinear soil behavior are incorporated factors that modify the seismic response of a response spectrum in rock (linear behavior). In this study, nonlinear site response analysis has been performed for 50 soil profiles in an attempt for covering a wide range of shear wave velocity profiles using the software DEEPSOIL V.7. For this purpose, 06 seismic records have been spectrally adjusted to uniform hazard spectrum of 475, 1000 and 2475 years of return period. Subsequently, a comparison of the results obtained from the site response analysis with the parameters stipulated in the Peruvian Seismic Design Code E.030 (2018) was made, in order to determine the likelihood of these for the construction of design spectra. Discrepancies in the ranges of Vs values that this standard considers for the classification of soils and the factors that determine the width of the plate of the design spectrum have been found.
