Prepared by the Disproportionate Collapse Mitigation of Buildings and Other Structures Standards Committee of the Codes and Standards Activities Division of the Structural Engineering Institute (SEI) of ASCE

Standard for Mitigation of Disproportionate Collapse Potential in Buildings and Other Structures, ASCE/SEI 76-23, provides a consensus perspective for mitigating disproportionate collapse. It describes minimum requirements for planning, assessment, analysis, material selection, design and detailing, construction, and qualification testing to mitigate disproportionate collapse of new and existing buildings and other structures.

The performance-based approach in this standard allows engineers maximum flexibility when finding solutions. Guidance is given about risk assessments and avoidance, as well as characteristics that enhance collapse resistance including the strength, ductility, deformation capacity, and robustness necessary to resist collapse without exceeding relevant limit states. It includes threat-specific and non-threat-specific methodologies and identifies direct design and indirect design approaches.

This standard is intended to address the same structures covered by ASCE 7, Minimum Design Loads and Associated Criteria for Buildings and Other Structures, and is written in mandatory language, with the expectation that it could be referenced by building codes or contracts documents.

Standard ASCE/SEI 76-23 provides essential guidance to structural engineers, architects, and those engaged in preparing and administering local building codes.
