SEAONC Rating System for the Expected Earthquake Performance of Buildings

摘要

There is an unmet need for information and terminology that non-engineer stakeholders can use to compare the seismic performance of different buildings and to make facility-related decisions. This paper presents a ratings system under development by the Structural Engineers Association of Northern California (SEAONC) Existing Buildings Committee (Building Ratings Subcommittee) intended to communicate information about seismic risk of buildings to the general public. It utilizes existing evaluation methodologies, and translates their results into a format that is easily understood. Included are the findings from an ATC workshop held in March 2011, which gathered input from potential rating system users, including owners and individuals from the real estate and insurance industries. Also included is an outline of the rating system as it relates to the standard known as ASCE 31-03.
