INSTRUCTOR:
William L. Coulbourne, P.E., F.SEI, F.ASCE
Purpose and Background
The purpose of this webinar is to acquaint the participants with the many conflicts that might occur using ASCE 24-14 with the new flood hazard methods used in ASCE 7-22 Supplement 2. The ASCE 24 Standards Committee is currently working on revising the standard so it better aligns with ASCE 7-22, but until that work is complete there will be conflicts between the two documents that must be navigated. This webinar will only offer the authors suggestions about how to navigate the potential conflicts; the presentation does not represent a consensus of the ASCE 24 Standards Committee.
This webinar is part of a series of webinars that focus on the many changes that have been made to the Flood Load Provisions in ASCE 7-22 and published in Supplement 2. This webinar on using ASCE 24-14 with ASCE 7-22 is intended to give the user the tools necessary to perform the required analytical evaluations related to the flood hazard. 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. The last revision to ASCE 24 was nearly 10 years ago. 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 in the ASCE 7-22 flood provisions 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. Many load calculations have been revised so the latest design considerations are included in the ASCE 7 load standard. The webinar topics include flood design and climate change and flood load combinations and how these combinations are dealt with in both ASCE 7 Chapter 5 and the ASCE 7 load combinations in Chapter 2.
This webinar series will cover all of the changes to the flood load provisions and will include several examples to illustrate how to apply the formulas and what information is required in order to provide a complete flood design. Each webinar in the series will focus on the changes in ASCE 7-22 compared to the provisions in ASCE 7-16. The sessions 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 topic of climate change and flooding will be discussed as well as how the new flood load provisions can be used with the most recent version of ASCE 24-14. 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:
- Use the revised methods and formulas in ASCE 7-22 Chapter 5 to solve flood load problems for both riverine and coastal locations
- Find the appropriate 500-year flood level to use for design
- Explain how ASCE 24 and ASCE 7-22 are used together
- Explain how the documents might be in conflict with one another and become acquainted with some ways to navigate these conflicts
- Find and use the many resources available to perform flood load calculations accurately
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).
Who Should Attend?
Civil engineers, structural engineers, coastal engineers, architects, flood plain managers
Outline
