Crack width - Results

List of Results

The following list of result values is available to be presented in the graphical output:

UC	Value of unity check
UC+	Value of unity check for upper fibres
w+	Calculated crack width for upper fibres
wlim+	Limit value of crack width for upper fibres
UC-	Value of unity check for lower fibres
w-	Calculated crack width for lower fibres
wlim-	Limit value of crack width for lower fibres

Graphical output

Unity check (UC) is drawn in three colour scale.

Grey - UC is lower than 0,001 → Cracks does not appear and check is OK

Green - UC is between 0,001 and UC_lim → Cracks appear, but the values are lower than limit crack width, check is OK

Red - UC is greater than UC_lim → Cracks appear, the value is greater than limit crack width, check is NOT OK

and also calculated crack width per each FE is available

Numerical output

Presentation of results as a numerical output is possible via Preview and / or Table results. Three types of output brief table according the selected Value are available.

UC

The results for the most dangerous direction and surface are presented in one table.

UC+; w+; wmax+

The results corresponding to the upper surface.

The explanation of values is the following

Reinf	User defined standard reinforcement expressed as "upper reinforcement / lower reinforcement"
h	Thickness of the slab
Fibre type	Type of fibres which is used for calculation of capacity check
Dosage	Used amount of fibres
m₊	Dimensional bending moment in direction of principal stresses for upper fibres
n₊	Dimensional normal force in direction of principal stresses for upper fibres
s_ct+	Maximal tensile strength in concrete in upper fibres
f_ct,eff+	Effective tensile strength for upper fibres
s_s+	Maximal tensile stress in reinforcement in upper fibres
A_ct,eff+	Effective area of concrete for upper fibres
e_sm-cm+	Difference between mean strains in concrete and reinforcement in case of steel fibre reinforced concrete in upper fibres
s_r,max+	Maximum crack spacing for upper fibres
w₊	Calculated crack width for upper fibres
w_lim+	Limit value of crack width for upper fibres
UC+	Calculated UC for upper fibres
Check	Status of check for upper fibres
