Steel reinforcement barsCrack growth modelSurface conditionsScatterFatigue behaviour predictionFatigue cracks tend to initiate on the rebar surface and therefore, the surface conditions may control their fatigue behaviour. This study investigates the influence of surface microstructure and roughness dispersion ...
An experimental study on the bond strength between reinforcement bars and concrete as a function of concrete cover, strength and corrosion level Cement Concr. Res.

The results showed that the use of a MLP neural network approach could be quite effective in automating the identification and location of embedded steel reinforcing bars from a radar investigation. Accurate estimation of depth, or cover, requires a reliable knowledge of the dielectric properties of...

Investigations on the fatigue strength of steel reinforcement bars (rebars) mainly involves fatigue tests with hot rolled (HR) and cold worked (CW) steels. However, in the last few decades, HR and CW rebars were replaced by quenched and self-tempered (QST) rebars with hardened surface layer....
This study took nine input parameters into account; surface area of the specimen (SAS), water/cement ratio (w/c), CS of concrete (f′c), concrete cover (c), bond length (Lb), diameter of reinforcement bars (d), type of reinforcement bars (Tb), yield strength of reinforcement bars (...
Keywords: CFRP bars; hybrid reinforcement; continuous beams; flexure 1. Introduction Reinforced concrete (RC) is widespread in civil infrastructures around the world, accompanying the progressive development of concrete materials [1,2,3]. Conventional steel bars in RC elements are subject to corrosive...
