Basic Prestressed Concrete Design Part 4: Prestressing Force-Basic Prestressed Concrete Design

Basic Prestressed Concrete Design - Session 4 Handout

Pdf Summary

The document discusses the design of prestressed concrete beams, focusing on code requirements and design examples. The design procedure includes calculating stresses after the release of the prestressing force, controlling top fiber tension stresses, calculating losses of prestressing force, and checking for compressive and tensile stresses at different load conditions. The document also covers the use of harping strands to reduce stresses, as well as the addition of non-prestressed top steel to control tension stresses. The design example provided shows the calculations for checking stresses at release and service conditions, as well as the steps taken to address any issues with stresses exceeding the allowable limits. The document concludes with a summary of the lectures covered in the program.
