Target Structural Reliability Analysis for Tsunami Hydrodynamic Loads of the ASCE 7 Standard

Abstract

AbstractMany coastal areas in the United States are subject to tsunami hazard. The public safety risk has been partially mitigated through warning and preparedness of evacuation, but community disaster resilience requires that critical and essential facilities provide structural resistance to collapse. Furthermore, there are coastal communities in the states of Alaska, Washington, Oregon, California, and Hawaii where there is insufficient time for evacuation. The Tsunami Loads and Effects Subcommittee of the ASCE/Structural Engineering Institute (ASCE/SEI) 7 Standards Committee has developed a new Chapter 6, titled “Tsunami Loads and Effects,” for the 2016 edition of the ASCE 7 standard Minimum Design Loads for Buildings and Other Structures (Minimum design loads for buildings and other structures). The new ASCE 7 provisions for tsunami loads and effects implements a unified set of analysis and design methodologies that are consistent with probabilistic hazard analysis, tsunami physics, and reliability an...
