The Design of Post-Tensioned Floors

Learn how to size the structural members and go through the design of a post-tensioned column-supported floor.

This topic explains the way to handle the intricacies of real-life floor systems, such and openings, steps, changes in member thickness, column drops, panel and discontinuous tendons that add complexities specific to post-tensioning, and what the hyperstatic moments are, and why you need to account for them in your designs. The step by step design example shows how to apply the ACI 318 code requirements to the design of post-tensioned floors.
