Tips for Designing with Post-tensioned Concrete

Have you wanted to jump into the world of PT design, but have hesitated due to a lack of experience on the subject?  Typical undergraduate or even graduate engineering course work may offer a brief overview of PT design, but a thorough, in-depth education on this design method is not commonplace in most universities.  However, there are many resources available to engineers who wish to enhance their skills and try something new!

In the October 2017 SE University session, Otto Schwarz, PE, SE, with Ryan Biggs | Clark Davis gave a talk on Post-Tensioned Concrete Analysis and Design.  Otto referenced several resources that are helpful to the novice PT designer.  Otto’s presentation was aligned with the methodologies presented in Prestressed Concrete Analysis and Design Fundamentals by Antoine E. Naaman which offers a comprehensive source of information for design professionals and students.  Also, the Post-Tensioning Manual published by PTI and the PCI Design Handbook offers additional design examples and useful material information and reference tables that were used in Otto’s presentation.

Otto also mentioned the PTI Technical Notes and FAQs which are available free of charge and cover a range of subjects related to post-tensioned concrete.  Otto specifically recommended FAQ no. 10 – The Use of Drop Caps to Reduce Flexural Reinforcement in Two-Way Post-Tensioned Slabs as well as Tech Note 01 – Effective Width & Post-Tensioning.

PT construction offers many advantages to conventional reinforced concrete and may be the solution for your next structural design.  From reducing cracking and building mass, to leaner member sizes and longer spans, PT concrete can provide an economical and efficient design.  Get started on your next PT design with the help of these resources!
