This value can be set in Concrete setting by using Advanced level or in 1D member data (advanced mode is ON), if defined. If normal concrete stress on un-cracked section at the most tensioned fibre of concrete cross-section is greater than this value, the crack will occur and the crack width will be calculated. There are two possibilities:
| 0 MPa | it means that crack width is calculated if there is some tension in cross-section |
| fct,eff | it means, that crack width is calculated only in case that normal concrete stress on un-cracked section at the most tensioned fiber of concrete cross-section is greater the mean value of the tensile strength of the concrete effective at the time |
