- Calculation of crack width – refer to Annexes L and M Minimising cracking due to restraint. Limit temperature rise. Reduce restraints. Use concrete with low thermal expansion. Use concrete with high tensile strain capacity. Apply prestress.
- According to Eurocode (EC2 EN 1992), the de-sign crack width can be determined using the fol-lowing expression w k = sr,max sm cm (1) where, w k = design crack width; sr,max = maximum crack spacing; sm = mean strain in the reinforcement; cm = mean strain in concrete between cracks. In the expression (1) sm - cm may be calculated as: E s s E s e p eff.
Issue:
Minimal reinforcement area calculated in Robot Structural Analysis for panels with reinforcement type label having crack width set as 0.1 mm is smaller than for 0.2 mm or 0.3 mm for EN 1992-1-1 code.
Calculation of crack width. S r,msx (Maximum crack spacing) = 32.25 cm (case spacing = 170 mm ≤ 5(c+φ/2) = 205 mm) s r,msx = k 3 c + k 1 k 2 k 4 φ/ρ p,eff s r,msx = 3.435 + 0.80.50.42512/0.01 = 322.46 mm with. Download update option file pes 2009 pc.

Causes:
Stress limit in steel as defined in the formula (7.1) is disregarded for crack with set as below 0.2 mm

Solution:
1. Calculate required area of reinforcement with crack width set as 0.1 mm2. Calculate minimal area of reinforcement with crack width set as 0.2 mm
3. Assume larger of these two values
