Results in RF-CONCRETE Members
Some parameters must be defined for the comparative calculation with RF-CONCRETE Members.
In Window 1.1 General Data, the governing load case must be selected for design in the Ultimate Limit State tab and the Serviceability Limit State tab. For the SLS design, the Activate creep and shrinkage check box must be selected as well.
Then, you can directly define the creep coefficient and the shrinkage strain in Window 1.3 Cross-Sections.
In Window 1.6 Reinforcement, the reinforcement diameters and concrete cover must be specified as follows.
If the Deflection Analysis is selected (see figure on the left) in the Serviceability tab of Window 1.6 Reinforcement, the additional Window 1.7 Deflection Data appears.
The recommended deflection of ℓ /250 is the default limit value.
The [Calculation] provides the maximum deformation value of 18.9 mm in the center of the member, confirming the manual calculation. The result is below the limit value of ℓ /250.
The following figure compares the deformations for state I (uncracked sections) and state II (cracked sections). The crack formation leads to a significant increase in the deflection.
