Limiting value wmax for the calculated crack width and definition of decompression
Eurocode 2 part 2: Design of concrete bridge structures 7.3.1 (105)
Recommendation
The recommended values of the calculated crack width wmax for relevant exposure classes are given in Table 7.101N.
The decompression limit requires that all concrete within a certain distance of bonded tendons or their ducts should remain in compression under the specified loading. The recommended value of the distance is 100 mm.
