Force/Stresses Report
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.
CIP RC/PT Girder uses the forces on the composite section (i.e., element results) and section and cross section part restraining forces due to time effects, if applicable, to compute the curvature on the section and the axial strain of a particular cross section part, e.g., at the CG of the box girder. The Top Stress and Bot Stress columns show the top and bottom stresses for the box girder. Compressive stresses are negative and tensile stresses are positive. These stresses are computed using the equation, P/A +/- My/I.
