Superposition Rules are used to combine the contributions of the individual natural modes in the final Seismic result including all. As shown in the image below, in the pull-down menu, the options are: ABS - Absolute values SRSS - Square Root of Sum…

The RM mode superposition method is a special superposition method to get the maximum of all components of the result vector considering all corresponding forces and/or deformations. The total result vector for each mode uses factorized natural modes…
