For the PT experts out there: a contractor is asking if they can pour a 24" deep PT beam in two lifts. The bottom 12" of the beam is in the slab and the top 12" is an upturn, so it does make sense from a constructability standpoint. However, calculating the horizontal shear flow at mid-height is greatly complicated by the presence of PT. There is also the issue of the dead and stressing ends being near the joint.
Any comments or advice?
