Hi,
Just want to verify and seek your opinion regarding on the aci code for prestressed member.
Is it the 500psi (3.5Mpa) and fc'/10 is the maximum precompression for the beam in high seismic zone?
And for the special moment frame, Is it not allowed to terminate the prestressing steel before the end/external beam of the frame? saying i have 2 span, 16m for span-1 and 5m for the span-2 and i will design the span-1 with post-tensioning while on the span-2 is i will design it conventionally(without pt).
Please see attached picture.
Thank you and happy new year!
