“…Focusing on compressive fatigue, the material degradation starts in the zones with larger compressive stresses, resulting in a redistribution of stresses along the cross‐section 1 . The compressive fatigue behavior of concrete is usually studied under uniaxial loading on cylinder specimens, for example, earlier studies 2–7 . The transfer of findings gained from material testing under prevailing uniform stress conditions into reliable design concepts for real structures against fatigue loading is still an open question.…”

The fatigue of concrete has been the subject of research for many years, and yet, there are still open questions. In particular, the fatigue-induced damage evolution accompanied by a stress redistribution process propagating through the concrete structure is still not fully understood. So far, there are only few experimental studies addressing the fatigue propagation through a material zone occurring, for example, in beams with a pulsating, nonuniform stress profile. To investigate the influence of such stress configurations on the material and structural degradation process, a measuring concept has been developed combining digital image correlation, fiber optic sensors, and conventional strain gauges. The presented experiments visualize the propagating fatigue degradation in the compression zone of prestressed concrete beams subjected to fatigue loading. Based on the developed measurement concept, the quantitative foundation for a comprehensive validation of design rules and material models accounting for concrete fatigue can be significantly extended.
