Residual stresses and imperfections in welded high-strength I-shape sections
- This article addresses the imperfections in high-strength steel I-shape sections caused by weld assembly. Load influencing imperfections are assumed mainly as deviations from the ideal shape (e.g. bending distortion) and longitudinal residual stresses. The quality of a numerically aided design of components exposed to either compression and/or bending is significantly dependent on those parameters. In this scope, major gaps in knowledge are still present. Eurocode (EC) is providing robust simplified models that date back to the 1960's and 70's. As a result, the ultimate limit state (ULS) is approached on a quite conservative basis. The investigations are presented in this article are aimed to give further guidance on these values in component-like specimens in the context of Eurocode.
