Contents :-

  •  Design Methods
    • Breakdown Of Floor Into Design Strips In Two Directions. Use This Software To Get Required Effective Post-tensioning Forces In Each Directions.
    • Banded All Tendons At Column In One Direction, And Distributed In The Other Direction. On The Design Drawings, Specify Total Required Effective Post-tensioning Forces At Banded Tendons, And Uniform Forces In Distributed Tendons.
    • When Tendon Less Than 140 Ft, Stress At One End. Otherwise Stress At Both Ends.
    • The Various Live Loading Conditions Should Be Consider By Input LL Zero At Some Spans.

Note :

  • The column moments are negligible for gravity punching design. Lateral loads, seismic and wind, should be supported by shear walls. Using equivalent frames to support lateral loads is not suggested.
  • By inspection, the deflections of slab do not govern PT concrete floor design. Otherwise, using PT concrete floor is inadequate for larger live load. (ACI 318, 9.5.4.1)
