“…The cyclic load signal is the superposition of a mean load mean (t) and a cyclic amplitude Δ (t, T), where T is the period of the load signal. Cyclic experiments are termed low cycle or high cycle depending on the number of cycles applied before failure occurs (Lee and Barr 2004). Once again there is no clear threshold, but low cycle ranges between tens to hundreds while high cycle ranges from thousands to millions.…”

“…Cementitious materials like PCM-concrete interface is inherently full of flaws, (such as pores, air voids, lenses of bleeding water under coarse aggregates and shrinkage cracks) (Lee and Barr 2004). The mechanism of PCMconcrete interface under fatigue loading can be divided into three distinct stages.…”

Stress analysis of RC structures that have been retrofitted by an externally bonded layer of Polymer Cement Mortar (PCM) based materials requires the development of a constitutive model of the PCM-concrete interface under static and fatigue loading. In this paper, the bending fatigue and shear fatigue tests were conducted to determine the interface fatigue degradation properties by using the J-integral method based on the energy equivalence. Substrate concretes with four different compressive strengths and interface roughness were applied to understand the effects of substrate concrete and interface roughness on the fatigue degradation properties. It was found that the failure characteristics of the PCMconcrete interface is similar to those of cementitious material and the failure modes of PCM-concrete interface has an important effect on the interface tensile and shear degradation relation and S-N relation under fatigue loading. The degradation relation is similar in the case that the failure mode is identical, regardless of the type of substrate concrete. The fatigue resistance of the PCM-concrete interface is inferior to that in the concrete cohesion layer.

“…Furthermore, they are easy to install and guarantee their dispersion throughout the whole concrete mass (Bentur and Sidney, 2007), something that corrugated steel bars cannot achieve. The repeated action of flexural stress generates a progressive loss of the structural properties of concrete, a process known as material fatigue (Lee and Barr, 2004;Vassilopoulos, 2010). The mechanistic methods of pavement design use material fatigue laws to determine the capacity of pavement to resist stresses, deformations and deflections imposed by traffic volumes and the weather (Papagiannakis and Masad, 2008).…”

The behavior in flexural fatigue tests of concrete containing metal fibers has not been extensively studied. Therefore, this Keywords: Steel fiber reinforced concrete, fatigue tests, pavements ResumenEl comportamiento en ensayos de fatiga por flexión de concretos que contienen fibras metálicas no ha sido ampliamente estudiado. Por esta razón, se planteó este estudio para determinar el efecto de la incorporación de fibras metálicas en concretos para pavimentos en ensayos de fatiga por flexión. Se diseñó una mezcla de concreto con módulo de rotura de 4.1 MPa a 28 días, a la cual se le dosificaron fibras metálicas de 35 mm de largo y 0.5 mm de diámetro en tres proporciones: 20 kg/m 3 , 40 kg/m 3 y 80 kg/m 3 y se dejó una sin adición correspondiente a la mezcla de control. Los ensayos de fatiga se realizaron sobre 68 especímenes de 100 x 100 x 350 mm, a una frecuencia de 8 Hz, se aplicaron esfuerzos entre el 80% y 90% del módulo de rotura de cada mezcla. Con la distribución de probabilidad Weibull se calcularon las curvas de fatiga con diferentes probabilidades de falla. En los rangos de esfuerzos estudiados, la vida de fatiga no aumenta para contenido de fibras de 20 kg/m 3 y aumenta un 6% para 40 kg/m 3 (0.5%) y 25% para 80 kg/m 3 (1%) comparado con la mezcla control.Palabras clave: Concreto reforzado con fibras metálicas, ensayos de fatiga, pavimentos
