Seismic Performance of Laterally Loaded Pile Group Using 3D Non Linear Finite Element MethodAuthors: D Neelima Satyam,Younus Mohammed Conference: International Conference in Advances in Analysis Design and Modelling GeoFlorida Feb 20 to 24 2010 Abstract Id 330 Abstract Submitted. Date: 2009-09-01 Report no: IIIT/TR/2009/138 AbstractIn seismic analysis of pile foundation, it is critical to evaluate the deformation property of soil and the response of pile member suffering large deformation. This paper presents a nonlinear Finite Element soil simulation of soilpile model based on mohrcoloumb model and its elastoplastic side is expressed as a winklers-type beam model. The nonlinear behavior of the group is studied by subjecting it to elcentro ground motion. Both series arrangement and parallel arrangement of piles is investigated by taking a parallel and series configuration of the pile group .Detailed study on the response of the pile behavior is studied by varying pile size, spacing, width of the pile group in the different soil conditions. The earthquake ground motion is applied at 3m ,15m and 30m from the surface . The behavior of the pile group is studied and results are compared with OpenSeesPL software (2006) .
