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

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

Course Length: 1.5 Hours

Purpose and Background

Stronger concrete, powerful design tools, and aspirational architectural layouts have made post-tensioned floors the choice of commercial and residential buildings. Little to none is covered in formal college courses, leading to the PT designs to be handled by specialty consultants. To remain competitive, making the right engineering assumptions, knowing the applicable provisions of the building code, this step by step presentation of a typical design gives you the basic knowledge you can rely on for the challenge of the state-of-the-art design of post-tensioned floor. This webinar provides the design engineers with the knowledge and skill they need for design of post-tensioned floor slabs. It provides an overview of post-tensioned floor design: what is it, why it is used and its benefits.

Primary Discussion Topics

• Serviceability and strength requirements of post-tensioned floors as specified in building codes and in practice
• Implementation of the building code requirements in design and good practice
• What post-tensioned floor design is
• Why post-tensioned floor design is used
• What the benefits are of post-tensioned floor design

Learning Outcomes

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

• Describe the latest requirements of the building code for design of post-tensioned floors
• Determine the basics of good design practice of post-tensioned floors
• Become familiar with the initial assumptions and their significance in selection of post-tensioned floor systems
• Identify the step by step design sequence of post-tensioned floors
• Improve the skill of designing economical and durable design

Webinar Benefits

• Gain knowledge of the current building codes applicable to post-tensioned members
• Discuss current design practice of post-tensioned floors
• Know the hardware commonly used in industry for post-tensioned floors
• Be able to handle the step by step and detailed design of post-tensioned floors
• Better select economical designs in post-tensioning
• Generate designs that benefit from the standard of practice
• Know and allow for the impact of construction practice in design
• Review and judge designs submitted by others, or generated by specialty software

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
• Post-tensioning suppliers
• Faculty engaged in teaching post-tensioning
• Graduate students

Webinar Outline

• Review required considerations prior to design
• Select a typical floor slab that features irregularities commonly met in practice
• Describe the steps necessary to design the slab from selection of thickness and material properties to detailing the construction drawings
• Discuss applicable provisions of building codes
• Demonstration of implementation

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]
