Short Description: Submitted By: ryandarwin Submitted On: 26 Mar 2012 Downloads: 164 Rating. CRACK WIDTH CALCULATIONS ACCORDING TO EUROCODE 2. Eurocode 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, wk, can be calculated from the following equation: wk = sr,max (εsm.

Crack Width Calculations 4 Design: general 4.1 Limit state requirements 4.1.1 Serviceability limit states 4.1.1.1 Cracking. Cracking of concrete should not adversely affect the appearance or durability of the structure. The Engineer should satisfy himself that any cracking will not be excessive, having regard to the requirements of the particular structure and the conditions of exposure. In the absence of special investigations, the following limits should be adopted.
A) Reinforced concrete. Design crack widths, as calculated in accordance with 5.8.8.2, should not exceed the values given in Table 1 under the loading given in 4.2.2. BS5400-4-1990 Introduction. What width is suitable for my project?
