“…7. The fatigue strength is generally reduced by 20-30% of the slow loading when more time-dependent fracturing and plasticity may evolve (Award and Hilsdorf 1974, Raithby and Galloway 1974, Maekawa and El-Kashif 2004. Under small stresses, the loading rate effect becomes negligible, because the time-dependency is much less in magnitude.…”

“…For example, the apparent fatigue life of materials may vary according to the stress frequency (Award andHilsdorf 1974, Raithby andGalloway 1974). Maekawa and El-Kashif (2004) extracted the accumulated fatigue damage of concrete solid by experimentally subtracting the component of time-dependent deformation and re-formulated more generic constitutive model for compression. This fatigue compression model is hereafter used inside the frame of multi-directional crack modeling (Fig.…”

Path-dependent fatigue constitutive models for concrete tension, compression and rough crack shear are proposed and directly integrated with respect to time and deformational paths actualized in structural concrete. This approach is experimentally verified to be consistent with the fatigue life of materials and structural members under high repetition of forces. The mechanistic background of the extended truss model for fatigue design is also investigated. The coupling of fatigue loads with initial defects is simulated and its applicability is discussed as a versatile tool of performance assessment.

This paper investigates the nonlinear creep behaviour of concrete in compression and its relationship with cracking under uniaxial compression (cracks developing parallel to the loading direction). A physical model explaining the nature and the role of linear and nonlinear creep strains is presented, together with a failure criterion for concrete under sustained loads. The model assumes that all nonlinear creep strains are due to concrete micro-cracking. The soundness of this assumption is checked against the experimental results obtained by the authors and by other researchers. The proposed model is shown to fit quite well the experimental results, for various load patterns and concrete ages. The model also proves that the affinity hypothesis between linear and nonlinear creep strains (usually taken for granted in the design for stress levels below 70% of concrete strength in compression) is no longer valid when concrete fails under a sustained load, because of the unstable growth of cracking. Concrete response in these cases is analyzed in detail and a simplified but realistic approach for the evaluation of the failure envelope in compression is proposed.

A fatigue behavioral simulation for steel fiber reinforced concrete (SFRC) subjected to high cycle repetition of loads is presented. The fatigue constitutive models for normal strength concrete developed in the past decades are extended to those for SFRC with regard to tension, compression and shear transfer along dispersed cracking. The hysteretic path-dependency of SFRC is extensively focused on as well as post-cracking tension softening, because it greatly affects the stress-strain amplitudes of SFRC inside structures. The interaction of multi-directional cracks is taken into account based upon the fixed crack approach for enabling the damage evolution under the principal stress rotation. The rate effect on the stress and strain relation is also formulated to take into account the nonlinearity related to both loading rates and numbers of cycles. These proposed models for SFRC are experimentally verified in view of S-N diagrams of flexural tension for practical use.
