Repeated loading, fatigue and influence of the load duration

Concrete long-term behavior is not limited to deformations caused by creep and shrinkage. Inelastic deformations are also caused by high levels of stresses. These deformations, due to microcracking phenomena in concrete, are related to fatigue under sustained loading and can also lead to failure of concrete under compression in the long term.
This phenomenon has been investigated by the Structural Concrete Laboratory by developing a constitutive model of concrete that includes the development of microcracking in concrete. This model has been validated by an experimental campaign and has led to further developments (constitutive laws for concrete) that are integrated in the research activities of the Laboratory.
