Episode Summary:

In this episode of The Structural Engineering Podcast, we sit down with Ryan Musgrove from Kramer Gehlen & Associates to dive into the world of post-tensioned (PT) concrete design. Ryan walks us through the fundamentals of PT systems, their advantages over conventional reinforced concrete, and what engineers should consider when designing and detailing these systems in the field. 

We discuss everything from tendon layout and serviceability checks to construction sequencing, stressing operations, and long-term deflection control. Ryan also shares some of the most common mistakes he sees in PT design and how clear communication between the engineer, detailer, and contractor can make or break a project.  

Whether you’re new to PT or have years of experience designing slabs and podium decks, this episode offers insights you can apply to your next project.  

Topics Covered:

- Basics of post-tensioned concrete and how it differs from mild-reinforced systems  

- Design considerations for slab geometry, tendon layout, and anchorage zones  

- Common field challenges during stressing and construction  

- Strategies for controlling cracking, camber, and long-term deflection
