The Role of ASCE 7-05 in Modern Seismic Design The American Society of Civil Engineers (ASCE) Standard 7-05, formally titled Minimum Design Loads for Buildings and Other Structures

Structural System Selection

Refers to ACI 318-05, AISC 341-05, etc., but adds specific seismic anchorage and continuity requirements. asce 7-05 seismic pdf

• The Maps: 7-05 used Maximum Considered Earthquake (MCE) ground motion maps based on a 2% probability of exceedance in 50 years (2,500-year return period). This was a shift toward more uniform risk.
• Site Coefficients ($F_a$ and $F_v$): The tables for how soil types (A through F) amplify ground shaking were revised significantly in 2005.
• Near-Fault Factors: This edition refined how to handle buildings located near active faults.

• Governs minimum loads (dead, live, wind, seismic, snow, rain, flood) for buildings and other structures; seismic provisions in Chapter 9 (with related content elsewhere).
• Intended for use with appropriate building codes (IBC editions contemporaneous with ASCE 7-05).
• Applies to the design of new structures and certain additions/alterations; does not replace local code amendments or jurisdictional requirements.
