Very short precast spandrels with "PRESTRESSING"
Very short precast spandrels with "PRESTRESSING"
(OP)
Hi!
I wonder what will happen to pretensioned precast spandrels, whose dimensions are 10ft long (simple span), 8ft tall and 8in thick.
Should I ignore all prestressing forces?
(Like 22 strands with 16kips pullout per each strand.)
Thanks!

How you handle the design would depend on the loading and the support system.

And a deep beam requires that the bottom steel be fully developed at the end supports. Not sure how you could do this with pre-tensioned strand. You would need bottom reinforcement with development length extending from the end if it is cast in!
