Anchorages and laps according to the next‐generation Eurocode 2—Overview and comparison to current provisions

Abstract

AbstractNew design provisions for anchorage and lap design, based on Model Code 2010 and the related background document, have been proposed for the next generation of Eurocode 2 (prEC2). In this article, the new provisions are examined and compared with the provisions in current Eurocode 2 (EC2). In the first of the three parts of this study, design examples are developed to show the practicability and effectiveness of the new design provisions. In the second part, parametric studies are carried out to check the generality of the new provisions and to clarify the roles of the main input parameters controlling the design of anchorages and laps. In the third part, a comparison is made between the predictions based on the new provisions and the results of a large database reported in the literature. To improve the fitting of the test results, adjustments are proposed for the coefficients appearing in the provisions of prEC2. The proposed adjustments—that may be introduced into National Annexes—ensure a sufficient level of safety of the new provisions for the design of anchorages and laps.
