Abstract	The present study analyzes the suitability of the formulas proposed in EHE, Eurocode 2 and ACI Building Code 318 for crack control in reinforced concrete by testing 14 full-scale beams subjected to pure bending. It also explores the effect of varying parameters such as diameter, steel ratio and compression reinforcement arrangement and analyzes the fit between the above theoretical procedures and the experimental findings (less favourable than expected in some cases). The article also discusses the considerable impact of certain parameters, such as steel ratio, on crack control, and the scant effect of parameters such as diameter, reinforcement spacing and the arrangement of compression reinforcement. Pursuant to the results obtained in this study, possible variations on existing formulas are evaluated, specifically on the formula exhibiting a tendency that came closest to reflecting the test results (EC-2), with a view to improving the fit between that formula and the experimental results.
