Prestressed Concrete Beam
Prestressed Concrete Beam
(OP)
Subject: Prestressed Concrete Beam (girder) in dunnage.
Top of girder is in tension.
How do we design longitudinal regular rebars (non-prestressed rebars) to resist the tension stress at top flange, need references / link.
Thanks.

RE: Prestressed Concrete Beam
It's relatively simple. Find your max tensile stress, use this combined with neutral axis depth to calculate the total tension force, and provide sufficient steel to resist it.
