EXHIBITOR: MNSEA Seminar & Tradeshow – Post-tensioned Concrete Structures

Post-tensioning is an efficient and economical tool for designing floor slabs and mat foundations. While the use of post-tensioning is widespread throughout the country, many universities do not offer a basic pre-stressed concrete course. This means many engineers learn on the job, often by simply operating analysis software. The session will cover the basic principles of post-tensioned concrete and illustrate how the proper use of post-tensioning can reduce the slab thickness, beam depth and rebar in a structural floor systems and mat foundations.

Post-tensioned concrete is typically used in two way slabs, one way slab and beams and mat foundations. The session will provide guidelines and tips for designing efficient post-tensioned systems while also highlighting areas to look out for that may indicate your design should be re-evaluated.

The performance and aesthetics of a post-tensioned floor system are highly dependent on the wall-to-slab detailing, layout of lateral system and construction accuracy.  Slip or release details between the slab and walls will be discussed with photographs illustrating the results if these details are poorly engineered or constructed.  The impact of the lateral system and shaft walls on building cracking will also be covered in conjunction with common construction issues that should be avoided.

Bryan Allred is the Vice-President of Seneca Structural Engineering and a licensed structural engineer who specializes in the design of reinforced concrete buildings utilizing post-tensioned floor systems. He is the co-author of the book “Post-Tensioned Concrete Principles and Practice” which covers the design of post-tensioned concrete structure from fundamentals to specific construction design and detailing. Bryan is a fellow of the Post-Tensioning Institute (PTI), a member of their Building Design and Education Committee and has given numerous PTI educational seminars across the country highlighting the use and benefits of post-tensioning.

The seminar will provide 3.0 PDH credits. Certificates will be distributed at the end of the seminar.

Suppliers from many areas of the construction industry ranging from fabricators to providers of design tools will be available to update us on products and services. Suppliers will be happy to answer your questions and provide solutions for your every-day challenges.
