The project goal was to develop a special module for ATENA software for prediction and modelling of durability and safety of transport structures.
This new module is now included in the new version of ATENA software v.5.6.

The parameters of the surrounding environment can be specified as a new boundary condition. This typically includes chloride concentration, CO2 content or relative humidity. Based on this information, the chloride or carbonation propagation is calculated in time taking into account the possible presence of cracks. When the propagation front reaches reinforcement, the corrosion model is activated, which results in the reduction of reinforcement area. This effect can be included in any reliability or strength assessment in ATENA calculation.
