Webinar: Part 1 – Design of Post-Tensioned Diaphragms
September 5, 2023 @ 11:00 am - 1:00 pm
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 1:
- Diaphragm Forces
- Diaphragm Analysis 鈥 Different Approaches
- Moment and Shear Diagrams
- Diaphragm Design 鈥 Two Methods Used 鈥 Wood versus Concrete
- 鈥淲ood鈥 Design Example
