5.5 Nonlinear Calculation

The results windows 6.1 to 6.4 are only displayed if the Nonlinear calculation option (state II) has been activated for the ultimate limit state, the serviceability limit state, or the fire resistance design in window 1.1 General Data (see chapter 3.1). Furthermore, there should be no design problems (see chapter 5.1.5).

The designs are performed with the reinforcement available in window 3.1 Provided Longitudinal Reinforcement.

The theory of nonlinear designs is described in chapter 2.4.

The results of the nonlinear design are sorted by ultimate limit state, serviceability limit state, and fire resistance designs. In addition, they are sorted by cross-sections, members, sets of members, and x-locations in individual windows for each of the mentioned categories. The concept of these windows corresponds to one of the "usual" serviceability limit state designs (see chapter 5.3.1).
