Modelling of Concrete Subjected to Cyclic Loading

The infrastructure of today depends heavily on concrete structures. Most of these structures are subjected to repeated loads, known as fatigue or cyclic loads: the loads weaken the structure. The aim of this project is to add to the knowledge of the deterioration phenomenon and to develop models that can describe the response of concrete subjected to cyclic loading. To deepen the understanding of concrete subjected to cyclic loading, the phenomenon was investigated on the meso-scale level and macro-scale level. It was found that the interfacial transition zones are crucial in amount and strength and the results of the analyses show an overall agreement with experimental observations.
