Abstract
The piled raft is a geotechnical composite construction, consisting of the three elements piles, raft and soil, which is applied for the foundation of tall buildings in an increasing number. In a parametric study 259 different piled raft configurations have been analysed by means of three-dimensional elastoplastic finite element analyses. In the study the pile positions, the pile number, the pile length and the raft-soil stiffness ratio as well as the load distribution on the raft has been varied. In the scope of this paper the results of the parametric study are presented and design strategies for an optimised design of piled rafts subjected to nonuniform vertical loading are discussed.
