Effects of actions due to group effect on the superstructure on pile groups

摘要

An approach based on design charts for the effects of actions due to group effects on the superstructure on pile groups is presented. Therefor an extensive numerical paramtetric study was carried out. A description of the numerical model and comparisons with field load tests and theoretical results are presented. The proposed computer-independent approach is a simplified analytical approach for practical cases to predict the average settlement of a pile group and the different pile resistances including the consideration of nonlinear pile behaviour. Finally, a design example is illustrated in order to demonstrate the applicability of this approach.
