Major revision now in force across EU member states. Introduces performance-based design as primary methodology, replaces force-based q-factor approach for buildings above 40m, and adds new site classification system based on VS30 with period-dependent amplification factors.

New edition published with expanded provisions for ultra-high performance concrete (UHPC) in structural applications, revised shear design methodology for deep beams aligning with Modified Compression Field Theory, and updated durability requirements for coastal exposure.

Public comment period open until 30 April 2026. Key proposed changes include climate-adjusted wind speed maps incorporating 2060 projections, new tsunami load chapter for Atlantic coastline, and revised seismic design categories for the Central and Eastern US.

Amendment introduces updated fire resistance design tables reflecting full-scale fire test data, new provisions for stainless steel structural hollow sections, and harmonised connection design procedures with EN 1993-1-8.

Preview edition released ahead of full 2027 publication. Notable inclusions are mass timber provisions for buildings up to 24 storeys, mandatory structural health monitoring for essential facilities in Seismic Design Category D through F, and updated progressive collapse resistance requirements.
