Název v původním jazyce

Finite element analysis of concrete pavement subjected to thermal loading

Popis výsledku v původním jazyce

Concrete pavements are subjected to loading by environmental actions and vehicle loads influencing their design and impairing the service time. A thermo-mechanical 3D finite element model is created in OOFEM software, designed to analyze the stress field induced by non-linear, non-stationary temperature characteristic daily cycles, both from summer and winter periods. This model uses a staggered approach, solving heat transfer followed by linear elasticity and contact problem. Heat transport model is calibrated with three year continuous monitoring of a real highway slab. Thermal loading is driven by air temperature and sun irradiation boundary conditions. The resulting temperature field is used to obtain stress response of a single slab 3.5x5.0x0.29 m, resting on elastic Winkler-Pasternak foundation. The interface between the slab and foundation is designed to allow separation of the slab when interface elements are subjected to tension. The results show that temperature field prediction is accurate for summer and winter period. The mechanical response of the model shows that stress induced by summer temperature is higher than by winter scenario, achieving maximal tensile stress 1.8 MPa and 0.7 MPa respectively.
