Pile group analysis
Use of three-dimensional finite element analyses for the study of the inelastic behaviour of piles and the calculation of the interaction between neighbouring piles, under static and dynamic loads. Study of the problem under elastic and inelastic conditions by use of appropriate constitutive models that model the behaviour of cohesive and cohesionless soils, and the soil-pile interface.
Investigation of the mechanisms of propagation for waves emanating from a loaded pile towards the neighbouring space, and the effect of the magnitude of the loading on these mechanisms. Use of the gained insights in the study of the behavior of pile-group foundations under static and dynamic loads, and the effect of pile-soil-pile interaction on the foundation’s behaviour, under loads of varying magnitude and frequency. Modification of the Ta-ger constitutive model, development of numerical models and computation of numerical results, with the intention of building a database to use for the calibration of macroelements.
Development of numerical algorithms (macroelements) for the analysis of the inelastic behavior of soil-foundation-structure systems under monotonic and cyclic loading. The mathematical structure of these macroelements will be based on the developed constitutive model of soil behaviour.
