Several nonlinear simulations of concrete and reinforced concrete slabs are performed using a layered model. Two Drucker-Prager criteria are employed to form a concrete plasticity model that is used for simulating the plastic yielding of layers. Moreover, an interaction with elastic Winkler-Pasternak subsoil model is considered for the case of a reinforced concrete foundation slab that is subjected to a concentrated loading force. All computations are done by the SIFEL solver using finite element method.

This paper is devoted to a computer simulation of coupled-thermo-hydro mechanical analysis of concrete structures. The attention is concentrated to concrete structures at early stage, when hydration heat evolution and moisture content changes can influence significantly the reliability and service life of these structures. The results of computation are illustrated by the simulation of a foundation slab, which is situated in the basement of the administration building Prague-Tìšnov, Czech Republic. The Künzel and Kiessl approach is used to analyze heat and moisture fields and it is extended by a set of climatic conditions and by a model of hydration heat evolution in concrete. The problem is solved using the open source program SIFEL.
