Same happens even I increase the beam size to 400圆00 and assume the same loading. Other than having a cover of 25mm and crack width requirement greater than 0.2mm, the tables of bar spacing/size is not applicable and calculation of flexural and shrinkage crack width are necessary.If the above 3 are correct, eurocode requirement seems too difficult to be met as shown in my spreadsheet that I would either have failed in minimum bar spacing (over reinforced) or failed in the crack width (0.16mm) for my 300x400mm beam. The shrinkage and flexural crack width shall be combined to check against the requriement.3. My interruption on Cl.7.3.1 in BSEN1992-3 about the crack width requirement is correct, and the crack width requirement is as strictly required to 0.16mm in my case.2.
