By activating the Analysis options command, the Analysis options window (Figure 166) is opened. The type of analysis, Linear or Nonlinear, must first be chosen. Nonlinear analysis allows the user to consider the crack propagation. Linear analysis does not consider any cracking, even for pre-cracked conditions.

Depending on the type of analysis, changes to the Tensile strength, or the Uplift Pressures under cracked conditions, or to the Performance Criteria, these changes can be considered by clicking on the appropriate button (Figure 166).
