Load Combination Generator - enhanced with intelligent generation of default combinations

[TSD-3624] From investigation and customer feedback on the use of previous releases, it was found that many engineers were simply accepting the combination generator defaults which could produce many unnecessary combinations. Additional intelligence is now built into the Load Combination Generator to produce fewer combinations by default, appropriate to the content and design settings of the model. Since the Analysis and Design process’s speed and duration are directly related to the number of combinations (potentially geometrically), this could significantly improve performance.

  • For example for the US Head Code, ASD combinations* are not required in general where the LRFD code has been selected for steel design. Not generating the ASD combinations can halve the total number. Such superfluous combinations will no longer be generated by default in this circumstance potentially significantly improving performance.

    • *Note that ASD combinations are NOT required for foundation design for US Head Code models.
