Purpose and Background

The purpose of this webinar is to acquaint the user with the many changes that have been made to the Flood Load Provisions in ASCE 7-22 and published in a Supplement. The last major revision to the flood load provisions was made nearly 20 years ago and many changes to the practice have occurred since then. There have been many failure studies of flooded buildings and much research done at the university level and at the US Corps of Engineers since the last revision.

The major change is the adoption of the 500-year flood as the minimum design flood level for Risk Category II buildings. This change prompted many other changes related to the recommended flood design level for other building types as well as the inclusion of revised formulas for many different types of flood loads.

This webinar will be the first of several that will cover the changes to the flood load provisions. This first webinar will focus on the changes in ASCE 7-22 compared to the provisions in ASCE 7-16. It will cover the many substantial changes made to load equations including those for hydrodynamic loads, debris loads, wave loads, and flood load combinations. There are several examples included to help the user understand the differences between ASCE 7-22 and ASCE 7-16 and the magnitude of those changes on flood designs. The intended outcome is that the participants will understand what the revisions to the flood standard are and be able to apply them to real problems.

Benefits and Learning Outcomes

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

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

This course is worth .2 CEUs/2 PDHs. 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 30 days of the course.

How do I convert CEUs to PDHs?

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