Consideration of Imperfections in Combination Expressions

Tips & Tricks

RFEM and RSTAB provide the option to create load and result combinations automatically according to combination expressions defined in the standards. In this case, imperfections can be set differently for each combination expression.

For example, you can consider imperfections in the ultimate limit state designs. The serviceability limit state designs can be performed without imperfections. For this, select the ‘Differently for each combination expression’ check box. Furthermore, you can select the ‘Imperfection load cases...’ check box in the case of the ultimate limit state designs and clear the check box in the case of the serviceability limit state designs.
