摘要：
The scope of the paper is to present a macroelement for dynami csoil-structure interaction analysis of pile-group foundations. The new macroelement is based on the single pile macroelement proposed by Li et al. (2016) and considers pile group effects. The principal features of the macroelement are first presented. Then, a discussion on an appropriate way to treat pile group effects is undertaken. It is proposed to introduce these effects by means of a decoupled rheological model (composed of an assembly of springs and dashpots) and dynamic interaction factors. The non-linear behavior is concentrated at the level of each pile using the aforementioned single pile macroelement. The performance of the new macroelement for dynamic soil-structure interaction pile-group problems is validated using advanced finite element analyses. The advantages and limitations of the approach are finally discussed.
