Cracking is normal in reinforced concrete structures subject to bending, shear, torsion or tension resulting from either direct loading or restraint or imposed deformations. Cracks may also arise from other causes such as plastic shrinkage or expansive chemical reactions within the hardened concrete.

Download magellan spring 2010 map upgrade v393. Such cracks may be unacceptably large but their avoidance and control lie outside the scope of Eurocode 2-1.1.Cracks may be permitted to form without any attempt to control their width, provided they do not impair the functioning of the structure. A limiting calculated crack width, w max, taking into account the proposed function and nature of the structure and the costs of limiting cracking, should be established. W max is defined in the National Annexes. The recommended values are presented in Table 1 below.Table 1: Recommended values of w max (mm). ( Eurocode 2– Table 7.1Ν ).
Eurocode 2 Crack Width Calculation Excel
CRACK WIDTH CALCULATIONS ACCORDING TO EUROCODE 2Eurocode 2 (EN1992-1-1) proposes equations for the calculation of crack width, taking into account several parameters, like the concrete and steel strain and reinforcing bar diameters.According to Eurocode 2, the crack width, w k, can be calculated from the following equation:wk = sr,max (εsm –εcm), wheresr,max: the maximum crack spacingεsm: the mean strain in the reinforcement under the relevant combination of loads, including the effect of imposed deformations and taking into account the effects of tension stiffening. Only the additional tensile strain beyond the state of zero strain of the concrete at the same level is consideredεcm: the mean strain in the concrete between cracks. The difference εsm –εcm can be calculated from the following expression:, where:σs: the stress in the tension reinforcement assuming a cracked section.
