Crack Width Calculation Eurocode 2
- Two analytical approaches, for calculating the crack spacing and crack width, are presented. The first model is a modification of the conventional crack spacing model presented in Eurocode 2 and is valid for the case when cracking is caused by an external load.

I am designing a pumping station (water retaining structure) and I found difficulties in complying with the crack width requirement in eurocode based on the forces I obtained from my structural analysis, and I got a few questions regarding the procedures to calculate the design crack width in accordance with the Eurocode BSEN1992-1-1:2004 & BSEN1992-3 & CIRIAC660.
1. According to BSEN1992-3 Cl.7.3.1, If I am designing for a beam (300mmx400mm) in the substructure (tightness class 1, max water depth 3.9m), is that means the allowable crack width of the beam shall be limited to wk1 = 0.16mm (as hd/h = 3.9m/Min(300mm,400mm)= 13). And same shall apply to the column (400x400mm), ( hd/d = 3.9m/400mm = 9.75)?
2. According to Eq.3.13 in CIRIAC660, I could calculate the crack width due to thermal & shrinkage, but shall I combine it with the flexural crack width calculated from Eqt. 7.9 in BSEN1992-1-1:2004 to check against the allowable crack width limit (0.16mm)? Or the design will be OK if the two resulted crack width satisfy the limit individually.
3. According to 7.3.3(2) in Eurocode BSEN1992-1-1:2004, the crack control shall deem to be OK if either the maximum bar diameter or maximum bar spacing are satisfied, and direct calculate of the crack width is not required. But does it only refer to flexural crack width? Shall I still need to calculate and check the thermal & shrinkage crack width if those crack are expected to occur?
Sorry for my poor English and I have attached my design spreadsheet for your checking.
Many Thanks!!!!!!!!!!!
