Sažetak
Paper describes basic concept for numerical modelling of pile group system used for strengthening of old bridge foundation. The basic design concern is to take into the account interaction between the old pier footing, the new pile group system and surrounding soil. Two different methods were used for soil-structure interaction modelling. The first method, available in computer software Ensoft-GROUP 7.0, is based on semi-empirical correlations to predict nonlinear reaction of the soil due to pile displacement. The second method, available in software PLAXIS 3D Foundation, accounts for full 3D soil-structure interaction. Methods were compared and the effect of old footing on the load transfer distribution is validated.
