Design of Post-Tensioned Concrete Floor
Design of Post-Tensioned Concrete Floor methods
1- Breakdown two ways of floor into design strips in one direction and one-way slabs in other direction. Design strips work as continuous beams by banded all tendons at the column.
The perpendicular direction like multi-span one-way slabs, using distributed tendons.
2- Specify total required effective post-tensioning forces at banded tendons, on structural drawings,
and uniform forces in distributed
3- when tendon less than 140 ft, stress at one end. Otherwise stress at both ends.
4- the various live loading conditions should be considered by input ll zero at some spans.
