“…Experiments on structural elements under fatigue loading representative of traffic loads on bridges are not very common. The influence of cycles of loads that represent seismic actions has been studied experimentally (El-Bahy et al, 1999;Mander et al, 1994;Manfredi and Pecce, 1997;Marthong et al, 2016;Thomson et al, 1998). Such experiments use loads that result in stress reversals, a situation which is different from what happens in a bridge subjected to repeated traffic loads (Elfgren, 2015;Forrest et al, 2010;Schlafli and Bruhwiler, 1998).…”

This paper describes a web-based finite element program called portal of damage. The purpose of the program is the numerical simulation of reinforced concrete framed structures, typically buildings, under earthquakes or others exceptional overloads. The program has so far only one finite element based on lumped damage mechanics. This is a theory that combines fracture mechanics, damage mechanics and the concept of plastic hinge. In the case of reinforced concrete frames, the main mechanism of deterioration is cracking of concrete. Cracking in a frame element is lumped at the plastic hinges. Cracking evolution in the plastic hinge is assumed to follow a generalized form of the Griffith criterion. The behavior of a plastic hinge with damage is described via the effective stress hypothesis, as used in continuum damage mechanics. The portal that can be accessed using any commercial browser (explorer, netscape, etc.) allows to:

“…Both models give the same results in the case of monotonic loading. Thomson et al [16] and Picon and Florez-Lopez [17] have also proposed another model for low cycle fatigue within the framework of the lumped damage models. Those models are not described in this paper as the use of the Griffith criterion is enough to justify most of the results presented here.…”

This paper proposes a repairability index for damage assessment in reinforced concrete structural members. The procedure discussed in this paper differs from the standard methods in two aspects: the structural and damage analyses are coupled and it is based on the concepts of fracture and continuum damage mechanics. The relationship between the repairability index and the wellknown Park and Ang index is shown in some particular cases.
