Story Shears and Overturning Moments

Story shears and overturning moments are reported in the global coordinate system as P, VX, VY, T, MX and MY. The forces are reported at the top of the story, just below the story level itself, and at the bottom of the story, just above the story level below.

The sign convention for story level forces is exactly the same as that for frame elements with the bottom of the story corresponding to the i-end of the frame element and the top of the story corresponds to the j-end of the frame element. The story shears and overturning moments are always reported at the following locations; Global X=0, Global Y=0 and Global Z is as described in the above paragraph.
