The POI column shows the name or label of the POI and, for program-generated POIs, it is composed of a span number and a fractional distance into the span. For example, the POI labeled "Sp1.050" is for the POI at midspan in Span-1. User-specified POIs will appear here as well. The Location column shows the physical location of the POI on the box girder, relative to the start of the girder. The PtLoc column shows the location of one of the many unit vertical point loads automatically applied to generate influence lines.

The Axial, Shear and Moment columns show the axial, shear and moment composite responses at the POI due to a point load located at PtLoc.
