Projects of the First Period

The focus of the priority programme is the investigation and modelling of material degradation in the concrete structure. In the first funding period of the priority programme, damage mechanisms in the fatigue process were investigated experimentally, taking into account defined influences, described using damage indicators and visualised using imaging methods. Damage was modelled using different approaches and at different scale levels, initially for a few load cycles, and validated and calibrated using the damage indicators and visualisations. In the first funding period, the focus was on the consideration of the main load types of pressure, tension (transverse tension) and bending as well as influences from concrete compositions, load type and speed and environmental conditions.
