Before starting the design, you can check the settings of the reinforcement as described in Chapter Checking the Reinforcement.
The 'Not Valid / Deactivated' column in the table now shows only the numbers of the steel members that will be ignored for the design.
Click the button on the table toolbar to start the design. You can then follow the 'Calculation Progress' as seen in the Concrete design image. The program calculates the load combinations assigned to the design situation and performs the design.
