Course Length: 1.5 Hours

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 webinar.

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

• 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
