The tables give 2 possible solutions, either maximum bar size or maximum spacing. So they are really an envelope of solutions based on the crack width formula rather than an exact solution of the equation (as far a crack width calculation can be called exact). If you want to use different cover, make an assumption on bar size and the formula will give the maximum spacing you need. If you did this for 25 cover, you would get a less conservative answer than the tables as they are conservative to allow any bar size to be used for the spacing table or any spacing to be used for the bar size table. RE: Maximum Bar Spacing for Crack Control - Eurocode 2 (Structural). Remember the calculated value is actually a mean or average crack width and is based on an assumed bond strength. Actual maximum crack width could be + 50% or more. ![]() ![]() And on top of that there are a lot of restraint stresses that are normally not included in the calculations. So most designers take the easy way out and adopt the more conservative figure. Make sure you do not guarantee a maximum crack width based on the code calculations. En focus studio.
