RE: modal participation factor
for example, if you have a uniformly distributed excitation force and you want a quantifiable measure of the coupling to each of you modes then modal participation is proportional to the integral of (force) x (mode shape). normalization insures that the maximum value is unity.
Thompson or Weaver are good starting points
