Webinar: Part 2 – Design of Post-Tensioned Diaphragms

The webinar will cover the design of post-tensioned diaphragms highlighting the benefits of precompression to reduce or eliminate additional drag and chord reinforcement. The webinar will also discuss how concrete diaphragms should be modeled and how a traditional steel or wood diaphragm approach does not apply to a concrete membrane. Construction photographs and details will be shown to clarify the design intent.

Part 2:

• Diaphragm Design – Concrete Method Example
• Comparison between Different Methods
• Use of Precompression in Diaphragm Design
• Collectors and use of Omega Factor
• Detailing
• Chord Design
