Warning and errors

The following errors, warnings and notes may be occurred during the check of crack width

Number Type Description Description/Solution
N5/1 Note The crack is not appeared, because maximal tensile stress is lesser than cracking strength.  
N5/2 Note The crack is appeared, because maximal tensile stress is greater than cracking strength.  
E5/1 Error Check was not done, because plane of equilibrium was not found. To increase amount of reinforcement or to increase dimensions of cross-section or to increase quality of the used materials.
N5/3 Note Depth of effective area of the concrete in the tension is calculated only as MIN[(2.5*(h-d); h/2)], because member is in compression.  
N5/4 Note The maximum spacing of reinforcement cannot be calculated. The width of cross-section perpendicular to direction of bending moment resultant crossing the bar with maximum tensile stress will be taken into account.  
E5/2 Error There is no reinforcement inside of effective area of the concrete in the tension. To input some bars of reinforcement to inside effective area of the concrete or decrease cover of reinforcement.
E5/3 Error Effective area of the concrete is not created. To increase amount of reinforcement or to increase dimensions of cross-section or to increase quality of the used materials.
N5/5 Note Check is not done, because normal force and bending moments for quasi permanent combination are zero.  
N5/6 Note Check crack width satisfies, because the crack width is lesser than limit value.  
E5/4 Error Check crack width does not satisfy, because the crack width is bigger than limit value. To increase amount of reinforcement or to increase dimensions of cross-section or to increase quality of the used materials.
E5/5 Error Check crack width does not satisfy, because crack width is not calculated due to some errors during calculation. To increase amount of reinforcement or to increase dimensions of cross-section or to increase quality of the used materials.
