Overview and Technical Background To Development of Asce 7-16 Chapter 6, Tsunami Loads and Effects

Abstract eng:
In February 2011, the American Society of Civil Engineers, ASCE, formed a new subcommittee to develop design provisions for Tsunami Loads and Effects (TLE). There is currently no standard in the US for tsunami design, even though five Western states (California, Oregon, Washington, Alaska and Hawaii) are exposed to severe tsunami threats. The TLE subcommittee consists of 16 members and 14 associate members and spent four and a half years developing a new chapter for ASCE 7, Minimum Design Loads and Associated Criteria for Buildings and Other Structures. These design provisions have been approved by the main committee of ASCE 7 for inclusion as Chapter 6, Tsunami Loads and Effects, in the 2016 edition of the ASCE 7 standard. It is also being incorporated by reference in the 2018 International Building Code. This paper gives a brief history of tsunami design code development in the USA, and an overview of the new Tsunami Loads and Effects chapter of ASCE 7, highlighting how many of the loading expressions were developed based on laboratory experiments and post-tsunami observations. Laboratory experiments performed at the O.H. Hinsdale Wave Research Laboratory at Oregon State University, along with experiments at University of Hawaii at Manoa, Lehigh University, University of Washington, University of Ottawa and other research laboratories contributed to the development of loading expressions for tsunami effects on coastal structures. In addition, valuable information was gained from surveys of buildings and other structures damaged during the 2010 Maule tsunami in Chile and the 2011 Tohoku tsunami in Japan. The authors participated in field surveys after both events and gathered extensive information on structural damage for postevent forensic analysis. The results of these laboratory and field investigations have contributed significantly to the development of the TLE design provisions in ASCE 7-16.
