Originální abstrakt

Cement-based composites exhibit several attractive characteristics for application in civil structures like bridges, concrete pavements, cooling and wind tower buildings and also for strengthening existing structures. This paper introduces values of the basic fatigue mechanical parameters of concrete C30/37 and C45/55. This is attributed to the propagation of internal micro-cracks that may result in the propagation of macro–cracks and unpredictable failure. Fatigue phenomena related to metallic structures have been analyzed since the 19th century, whereas the behaviour of reinforced/concrete (RC) structures under cyclic loading has been studied for only a few decades. Fatigue crack propagation rate was determined on a three-point bend specimen and correlated with the applied stress intensity factor range (da/dN–K curve) corresponding to simple Paris law.
