Abstract:
The fiber section method is used to study the constantly changing process of reinforced concrete under flexural fatigue loads. The constitutive properties of average sections was deduced based on the existing constitutive properties of component materials, then the flexural fatigue performance of reinforced concrete was presented by fiber section method and was simulated by a computer program. The results of numerical simulations and tests indicate that the development of each fiber’s stress and strain is divided into two phases; the stress and strain redistribution on cross section of reinforced concrete flexural components under cyclic loads are presented. The curves of xc-n,εc1-n,εc1s-n based on the simulations are consistent with the test results. The approach and the computer program developed are practical for accelerating the analysis of fatigue behavior of reinforced concrete decks.
