Bridge Design Guide
flange of a Slab Beam or adjacent Box Beam as shown in Figure 3-7. ♦ For U-beam and X-Beams, place the phase line as shown in Figure 3-4 and Figure 3-5. 1. Place the phase line along the top flange of the beam. If the phase line is located along the top flange of the beam, the majority of the beam will be under the initial phase of construction.
