ASCE 7-05 (Minimum Design Loads for Buildings and Other Structures) is a landmark engineering standard that significantly reshaped seismic design in the United States. While it has been superseded by newer versions like ASCE 7-10, 7-16, and 7-22, many jurisdictions still reference the 2005 edition for existing building evaluations and certain retrofitting projects.
The ASCE 7-05 standard shifted from older "zone-based" seismic maps to a more refined approach based on spectral acceleration. The seismic provisions are primarily contained in Chapters 11 through 23. Uses Sscap S sub s (short period) and S1cap S sub 1 (1-second period) mapped values.
If you are using the 7-05 version today, be aware of the major changes that occurred in later editions: Risk-Targeted Maximum Considered Earthquake ( MCERcap M cap C cap E sub cap R
