Abstract

The second generation of the Structural Eurocodes is expected to be published by 2026. This article describes design provisions for laps and anchorages of normal ribbed reinforcement in Sections 11.4 and 11.5 of the final draft of the forthcoming version of Eurocode 2, the European Code for Design of Concrete Structures. This article outlines why and how design provisions have been modified, demonstrates the physical rationale for the rules and notes the evidence on which the justification is based. It also indicates the impact of the revisions.

The article gives an overview of the factors influencing anchorage and lap strength and presents a historic perspective on the development of the revised rules. The influence of each factor as represented in current and revised are then compared. The revised rules are then validated against test databases for anchorages and for tension and compression laps, and the impact of the revisions on design practice for selected situations are briefly examined.
