Item Open Access 2D nonlinear soil response based on the influence of vertical component in near-fault conditions(Santo Domingo : Instituto Tecnológico de Santo Domingo, 2023) Germoso, C.; Placeres, L. Luis; Simonelli, A.; Penna, A.; Aliperti , D.In this study we propose a numerical simulation based on a parametric 2D soil response analysis, in order to analyze the influence of vertical acceleration in near fault conditions. Soil nonlinearity will be considered in a real time manner from the offline construction of a parametric solution, where shear modulus and damping factor of soils are modeled as equivalent linear relations of the shear strain. The algorithm proposes an online integration that proceeds by particularizing the parametric solution for the shear modulus and damping parameters, and then update it, from the just calculated solution, regard the level of deformation [4]. The aim is to be able to compute very fast solutions to non-linear soil dynamics and to examine the dynamic response of different stratified surface configurations considering the nonlinear characteristics, in order to evaluate the role of the vertical component of the seismic movement.
