Post-Tension Slabs: Analysis, Design & Construction - Course No S02-035 - PDH credit course

Oct 24, 2026

Training material on post-tension slab systems, covering how the method works and the roles of key components such as anchors, ducts, and tendons. It outlines construction steps, compares advantages and disadvantages, and discusses post-tension types. The course provides systematic design steps including loading conditions, member force definition, section depth/thickness selection, tendon force and profile selection, stress checks, post-stress loss evaluation, and flexural and shear strength verification.

FAQs

How does a post-tension slab work and what are its main components?

It uses post-tensioning with anchors, ducts, and tendons. The course explains how these components work together to apply and manage post-stressing through the slab system.

What design checks are required after selecting tendon force and profile?

The material requires checking final and initial stresses, verifying allowable stresses for concrete and tendon, and assessing stress distribution based on the tendon arrangement.

Which pre-stress losses and strength verifications are covered in the procedure?

The procedure includes checking pre-stress losses, including friction losses, anchorage set slip, elastic shortening, and long-term losses. It also covers flexural strength and shear strength checks.
