This webinar was co-sponsored by ASCE's Structural Engineering Institute (SEI) and ASCE Continuing Education

Instructor:  Bijan O. Aalami, Ph.D., M.ASCE

Purpose and Background

This webinar provides in clear language an in-depth background to the application of post-tensioning. Catch up with the know-how you need but did not receive in college courses for design of post-tensioned structures. Step beyond the basics to learn the best options to model tendons: hyper-static effects. judicious tendon layout, cracking, and more. You will develop the skill to select and use the optimum software in your PT design work. This webinar answers the questions that most design engineers encounter but for which they do not find satisfactory answer. A familiarity with post-tensioning design basics is required to attend this webinar.

Primary Discussion Topics

• Structural modeling of floor systems—load path for service and safety
• One-way and two-way systems
• Post-tensioning selection and tendon layout
• Tendon modeling for design
• Hyper-static actions: cause and calculation
• Application of allowable stresses: precompression
• Beams, slab bands, flanged beams, and post-tensioning

Learning Outcomes

Upon completion of this course, you will be able to:

• Master the application of design concepts to practical problems
• Identify the shortcomings of common design practice and means for their improvement
• Design more economical floors, with improved service and safety properties

Webinar Benefits

• Describe In-depth understanding of post-tensioning principles and application
• Becoming familiar with the background and significance of building code requirements for design of post-tensioned members
• Better skilled to handle the design of complex post-tensioned projects

Assessment of Learning Outcomes

Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and fill in the blank questions).

Intended Audience

• Civil and structural engineers
• Building officials
• Contractors
• Faculty teaching concrete course
• Students of concrete design

Webinar Outline

• Definition and application of load path for design of post-tensioned floors
• Tendon layout and modeling
• Determination of post-tensioning actions and their implementation in design
• Basics of load balancing and other tendon modeling options
• Hyper-static actions: cause, determination, and implementation in design
• Application of building code requirements

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion

To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
