Rebar Stress
Rebar Stress
(OP)
Folks,
In 'Notes on ACI 318-08' P6-31 the bar area calculation for tension and compression reinforcement uses different steel stresses e.g. 60 and 58.7 psi.
Does anyone know the reason for the two stresses or is it a typo?
many thanks

RE: Rebar Stress
The beam is designed for the compression strain in the concrete at the top of the beam at 0.03. Since the top bars are a bit lower, the strain there is lower. Thus the bars are not stretched to their full 60 ksi.
