A review on the effects of cracking and crack width on corrosion of reinforcement in concrete
Structural Concrete, 2023AbstractIt is widely known that corrosion is one of the main problems that reinforced concrete structures may endure during their life‐cycle. This problem is usually tackled in a prescriptive manner, by limiting the crack width allowed to occur during structures' service life.

Numerical prediction of crack propagation and crack widths in concrete structures
Engineering Structures, 2009The paper deals with the numerical prediction of crack propagation and crack widths in concrete structures. The early stages of cracking, characterized by distributed micro-cracking, are described by a smeared crack model with rotating crack directions, whereas the subsequent formation of a macro-crack is described by embedding a discontinuity in the ...

Uncertainties of Crack Width Models
2017Crack widths for verification of serviceability limit states can be calculated by simplified formulas provided by codes of practice or by numerical analysis based on nonlinear finite element methods. Authors performed a pilot study with the aim to develop a methodology for assessment of model uncertainty involved in the crack width analysis ...

Influence of cracks and crack width on penetration depth of chlorides in concrete
Revue européenne de génie civil, 2009Chloride induced reinforcement corrosion is the main durability problem for concrete structures in a marine environment. If the chlorides reach the reinforcement steel, the latter will depassivate and start to corrode in presence of air and water. Since the corrosion products have a larger volume than the initial products, concrete stresses are induced,

Determination of crack spacing and crack width in reinforced concrete beams
Structural Engineering and Mechanics, 2003In this paper spacing and width of flexural cracks in reinforced concrete beams are determined using two-dimensional finite element analysis. At early loading stages on the beam the primary crack spacing is based on the slip length, which is the development length required to resist the steel stress increment that occurs at a cracked section on the ...
