main mode

Untitled.jpgwhio can tell me what the mean of main mode .. and i used UBC97 CODE and what this method

If a main mode is set to 0, then the combination sign calculated from the formula for calculating CQC or SRSS combinations will be assumed.

The bottom part of the dialog box selects the Default type of seismic calculations to be applied in the case of seismic combination:

 

  • CQC - Complete Quadratic Combination
  • SRSS - Square Root of Sums of Squares
  • 10% - 10% double sum
  • 2SM - double sum.

what i must used in this code ??
