2.8.3.1 Concrete in compression area

Concrete in compression area

For the serviceability limit state design, the program calculates using the mean strengths of the materials. In the compressed area, it is possible to choose between a parabolic and a parabolic-rectangular distribution of the stress-strain diagram.

The settings are specified in the Material Properties tab of the Settings for Nonlinear Calculation dialog box (see Figure 3.12). This dialog box can be accessed in the Serviceability Limit State tab of window 1.1 General Data by clicking the button shown on the left (see Figure 2.130).
