Abstract: This research is a bout the study of the behavior of inclined micropiles due to seismic loading. Analysis is done by using a dynamic finite element modeling. The soil media is assumed with Rayleigh damping and micropiles are modeled like elastic beam elements. The structure of the micropiles are defined as a single degree of freedom which is composed by a concentrated mass and a column. The first chapter of this article is involved the technical litreture of the behavior of inclined micropiles. The second post is explained about the numerical model used in this study. The third part is about the analysis on influence of micropiles inclination on the seismic behavior of a group of micropiles embedded in a homogeneous soil with a uniform stiffuness and the fourth part is done the same analysis on inclined micropiles which are in a soil layer with a depth based in the increasing stiffness. The results of this research give the valuable date about the influence of micropiles inclination on dynamic amplification and or the seismic induced internal forces in micropoiles.
