Q: How do I know what SCF is used for determining a fatigue CDR?
REV 7.00

A: The SCF used depends on the classification of the joint which depends on the loads in the chord and the braces. What MOSES does is to assign a fraction of each type of joint to the joint in question; i.e. the joint is A K joint, B T joint, and C X joint and A + B + C = 1. So the SCF that MOSES uses is:

     SCF = A * SCF_k + B * SCF_T + C * SCF_x

The Joint SCF Summary provides the SCFs for all 3 joint types and for Punching Shear the factors A, B, and C are printed. For Fatigue, however, this is simply too much information to present. The only way you really know which SCF is being used is if you use -cls_mean yes. Otherwise, you get a new joint classification for each force response operator.
