Thank you, EZBuilding and Celt83,
I am using old post-tensioned software, POSTEN, for post-tensioned design and RAM Elements for lateral analysis since the ramp beams per frame are not in the same elevation.
Are the hyperstatic moments from the PT same as the secondary moments?
Are the...
EZBuilding,
Thank you for your reply. From the post-tensioned design under gravity loads, I only need 3#10 top bars for negative moment (actually per Asmin=0.004Act) at face of column in the beam. When I use RAM Elements for the lateral frame analysis, I will need 7#10 top bars for negative...
If the mild steel provides full design capacity, the contribution from tendons is very limited except for deflection and crack control. I saw two sets of parking deck design drawings with similar layout, they did not have heavy mild steel reinforcing in the PT moment frame beams. I just wonder...
Hi,
I am working on a post-tensioned concrete parking garage and using PT moment frames for lateral load system. When I design the PT beam under gravity loads alone, it only needs 3#10 for negative moment at face of column which is per the minimum mild steel reinforcing requirement. When I run...
