Design of Post-Tensioned Concrete Floor methods

1- Breakdown two ways of the floor into design strips in one direction and one-way slabs in another 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.
