Precast/Prestressed Girder Help

Full Beam and Half Beam

Precast/Prestressed Girder is intended for the design of beams that are symmetrical about the midspan. As a result, only values for half a beam are shown in the output for stresses. However, for vertical shear, horizontal shear, ultimate capacity, and reinforcement, full beam results are shown. For each location, Precast/Prestressed Girder determines which point is critical between corresponding symmetrical points on the left and right halves of the beam. For example, on the output under "Final Stresses - Positive Moment Envelope," Precast/Prestressed Girder compares the stresses due to total loads at the points located at 0.1L and 0.9L. The point with the highest stresses is reported in the output.
