Washington State School Seismic Safety Assessment Project

Natural & Man-Made Disasters

This session will earn 1.0 PDH

Abstract: The Washington State School Seismic Safety Assessment Project (WASSSAP) is an ongoing project within Washington State to evaluate a portion of the state's public K-12 schools for their seismic risk. Phase 1 of the project seismically evaluated 222 school buildings and was completed in June 2019. Phase 2 of the project will seismically evaluate an additional 350 school buildings and is scheduled to be completed in June 2021. Washington State has over 4,000 permanently occupied K-12 school buildings in total. The project includes the use of three separate seismic evaluation methodologies. School buildings are evaluated using ASCE 41 Seismic Evaluation and Retrofit of Existing Buildings Tier 1 procedures, FEMA 154 Rapid Visual Screening procedures and the Earthquake Engineering Research Institute’s Washington State School Earthquake Performance Assessment Tool (EPAT). The results obtained from the use of each tool are compared and contrasted. In addition, an overall assessment of the state’s schools vulnerability to large earthquakes is provided.

Learning Objectives:

  • Learn about the small cost of big increases in seismic resilience.
  • See how big increases is strength and stiffness, combined with better detailing, can greatly reduce catastrophe losses and they make more sense under standard engineering economic principles.
  • Learn about economic research that debunks fears that slight increases in construction cost have catastrophic impacts for the building industry.
