Analytical and Experimental Investigations of Crack width for RC Beams in Bending

Although cracks do not considerably impair the resistance of reinforced concrete elements, they definitely affect the durability and appearance of structures. The control of crack width and spacing is a convenient approach in engineering practice. The width of a crack is characterized by high variability and the formulas suggested by design codes vary significantly. In the presented paper, the crack widths are derived using analytical methods recommended by several design codes and compared with the results of experimental investigations.
