Precast Concrete Reinforcement - NPCA

Dec 11, 2015  Concrete beams reinforced with post-tensioning or prestressing can be designed to span longer distances than beams reinforced with other methods because they can generally be thinner and lighter. Additionally, the more slender beams provide extra clearance space and may be more aesthetically satisfying for context-sensitive designs.

Precast Design Engineering Handbook - Precast Concrete

The material properties used are 6000 psi concrete in the precast element and either 250 ksi or 270 ksi prestressing strands. For the beams and double tees, the capacities are somewhat independent of the available fire rating. However, for the Spancrete hollowcore plank, the fire endurance provided will have an effect on load capacity.
