Instructions for Live Webcasts

After registering for the event, you will receive an email with a URL link to join the presentation at the specified date and time. Log in at the specified time, view the entire presentation, and download a Certificate of Completion at the end of the presentation. The certificate of attendance is for 1.0 professional development hour (equivalent to 0.1 continuing education unit in most states.) Check back later for information on upcoming webcasts.

Groups who plan to view the webcast together will be allowed to download and complete a Multi-Viewer Registration Form during and immediately following the webcast.  Only one person needs to register for the webcast and that person is responsible for submitting the Multi-Viewer Form.  It is the responsibility of all group viewers to visit the certificate page following the webcast to print their own certificate.



The desire for cost savings can result in the use of thin concrete slabs; however, slab deflection performance is difficult to predict. Factors that influence deflection are not accurately known during the design phase because many parameters depend on conditions at the job site. Long-term deformations can result in costly issues and post-construction litigation.

This webcast will discuss deflection issues, parameters affecting deflection, and several deflection calculation methods. The variability of deflections and a reasonable range of predictions will also be discussed, concluding with recommendations for design practice utilizing off-the-shelf software.

Learning Objectives:

  • Recognize the types of problems that can be caused by excessive deflections
  • Identify the major factors influencing concrete slab deflection and the variability of deflections in the field
  • Understand differences between modern calculation prediction methods
  • Outline a practical approach for deflection design
