Interaction between the foundation plate and subgrade can be described by different mathematical - physical model.Elastic foundation can be modelled by Bathroom Fixtures different types of models, e.g.one-parametric model, two-parametric model and a comprehensive model - Boussinesque (elastic half-space) had been used.The article deals with deterministic and probabilistic analysis of deflection of the foundation plate on the elastic half-space.
Contact between the foundation plate Trigger Locks and subsoil was modelled using contact elements node-node.At the end the obtained results are presented.
