Evaluation of increase in the deflections of concrete specimens due to cyclic loading

Popis výsledku v původním jazyce

Fatigue is commonly defined as a process of permanent progressive changes in the structure of a material exposed to cyclic loading. With the improvement of properties of concrete, more slender structures are designed with higher live load proportion of the total load, hence higher vulnerability to concrete fatigue failure can be assumed. Many common structures, bridges and crane tracks, are exposed to cyclic loading which can result into accelerated crack propagation, higher deflections, structural stiffness reduction and consequently into failure fatigue. The paper presents a newly developed method for the calculation of the increase of deformations. This method uses the partial integration over compressive zone height in order to capture the real behavior and stress distribution of concrete specimens. This method represents an improvement of the standard approaches which appear to be very conservative.
