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