A Review on Fatigue Performance of Concrete Structures Part II, Material Parameters and Environmental Factors

Abstract

Fatigue is a critical issue for concrete structures subjected to repetitive and varying loads,particularly in infrastructure and transportation systems. This review paper presents acomprehensive overview of the current state of knowledge on concrete fatigue and identifies areasfor further research. Material and size factors that influence fatigue performance and lifeestimation of concrete such as concrete composition, internal moisture content and reinforcementare explored, along with environmental conditions such as presence of external moisture andseawater exposure. The paper also acknowledges the challenges associated with predictingconcrete fatigue life accurately due to the heterogeneous nature of concrete and its complexbehavior under cyclic loading.
