Crack Width Limitation According to DIN 1045-1
Crack formation is essentially unavoidable in areas where
concrete is subject to tensile stress. However, the crack width
should be limited such that proper use of the structure as well
as its appearance and durability are not compromised as a result
of cracks.
The limitation of crack widths according to
[1] DIN 1045-1 August 2008 Section 11.2 contains the following
checks:
- Check of the minimum reinforcement according to [1]
Section 11.2.2,
- Check of the crack width limitation given the determinant
action combination according to [1] Section 11.2.3 (Limiting
the crack width without direct calculation)
- Check of the crack width limitation given the determinant
action combination according to [1] Section 11.2.4
(Calculation of the crack width)
