Instructors:
Ian Nicol Robertson, Ph.D., P.E., M.ASCE
Gary Y.K. Chock, S.E., F.SEI, F.ASCE

Course Length: 1.5 Hours

Purpose and Background

Many coastal areas in the western U.S. are subject to tsunami hazard that is infrequent but potentially extremely destructive. The ASCE 7-16 Tsunami Loads and Effects chapter will become the first national, consensus-based standard for tsunami resilience for use in the states of Alaska, Washington, Oregon, California, and Hawaii. This webinar provides an explanation of the methodology for tsunami-resilient design of critical and essential facilities, tsunami vertical evacuation refuge structures, and other multi-story building structures. The ASCE 7 provisions for tsunami loads and effects implements a unified set of analysis and design methodologies with design maps based on probabilistic hazard analysis, loads based on tsunami physics, and a structural ultimate strength basis of design.

It will be helpful for participants who are engineers to review their fundamental knowledge of fluid mechanics before the starting this course.

Primary Topics of Discussion

• Tsunami risk categories and the scope of the ASCE 7-16 tsunami provisions
• Probabilistic tsunami design zone maps
• Analysis of inundation depth and flow velocity
• Structural design for tsunami effects
• Foundation design

Learning Outcomes

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

• Recognize the difference between tsunamis and other types of flooding events
• Discuss the scope of the tsunami provisions and how that improves community resilience
• Identify the terminology of the tsunami design provisions
• Recognize the probabilistic basis of the tsunami design zone maps
• Determine the design inundation depth and the flow velocity at a site
• Observe how the structural loads are calculated for various load conditions
• Know about designing the lateral-force-resisting system and structural components
• Discuss about scour and erosion effects and how to mitigate them
• Examine how the tsunami vertical evacuation refuge structure criteria are intended to achieve very high reliability for life safety

Webinar Benefits

• Learn about tsunamis and why they can be severely damaging
• Lessons learned from past tsunamis
• Understand the overarching requirements and intent of the ASCE 7 tsunami design provisions
• Learn about tsunami design zone maps
• Learn about what information is needed for the site before performing structural design
• Understand the various loads and effects generated by tsunami during inundation
• Learn how to proceed in design efficiently and what structural elements are more likely to be governed by tsunami effects

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).

How to Earn your CEUs/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 1 year of purchasing the course.

How do I convert CEUs to PDHs?

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