Abstract In this paper, the problem of a pile-raft foundation of a high-rise building located in Warsaw in typical soil and water conditions was presented. In order to describe the soil–foundation interaction, regarding load distribution, an analysis was made based on finite element method (FEM) with the use of the hardening soil with small strain soil model (HSS) in the ZSoil and Autodesk Robot Structural Analysis (ARSA) program. The article contains basic information about the pile-raft foundation, description of ground-water conditions together with the estimated parameters for the HSS model of soil applied in ZSoil calculation. It also shows a block diagram, as a kind of algorithm, presenting the proceedings in designing, modelling and numerical analysis between ZSoil and ARSA program. Own load distribution analysis in CPRF elements based on the numerical procedure enables the comparison with the measurements results of the load distribution carried out by Mandolini with associates in 2005.

Key Parameter

One of the basic roles of foundations is to safely transfer loads from the structure to the subsoil in a controlled manner. Often a key parameter in deciding whether the foundation was designed correctly is the value of settlement of the building and the ground around it. This paper attempts to numerically reproduce the measured settlement of a high-rise building using geotechnical parameters already available. For this purpose, numerical calculations were carried out using two constitutive soil models: the elastic-perfectly plastic model with Mohr-Coulomb plastic criteria (MC) model and the Hardening Soil (HS) model. The resulting settlement values were compared with surveying measurements taken during and after the building’s construction. In the summary the results obtained with the use of different constitutive models, the calculation process and the adopted soil parameters are analysed and discussed.
