Abstract

Since the National Emergency Management Agency’s seismic fragility function, developed in 2009, classified domestic buildings by structural type, numerous studies have used this classification. In 2021, the updated seismic fragility function adopted a slightly more complex classification logic, limited to concrete structures. Data for structural-type classification were derived from information in the building register, including primary use, floor area, permit date, and number of stories. To verify and improve the accuracy of the classification logic, a sample of approximately 1,800 from about 13,000 concrete buildings in a specific region was selected. Structural types classified by the logic were compared with those identified through road views provided by the Architecture HUB. The results confirmed that the existing classification logic requires revision to incorporate additional variables, including the sub-use of the building and the area-by-use on the first floor. The revised logic significantly improved classification accuracy by including those variables.
