Harmonic Response of Pile Groups to Dynamic Loading


Civil Engineering, University of Queensland


A completely general method of analysis for three-dimensional raked piles under harmonic excitation is discussed. The piles have been represented by a three-dimensional frame structure and the soil has been represented by a boundary element discretization scheme. A computer program has been written which carries out this analysis and produces a group stiffness matrix that can be included as a foundation stiffness matrix in the analysis of a superstructure. Results from this analysis have been compared with those available in the literature.
