Abstract

Mixed connections made of normal strength and high strength steels enable optimal material use to the forces acting on them. This leads to ecological and economic advantages through reduced material consumption and smaller weld geometries. Normative rules for buttwelded mixed connections of normal strength and high strength steels do not exist, therefore a design approach for such connections is to be developed in the research project “Effective design concepts for mixed connections in steel structures”. In addition, the design concepts already developed for butt-welds and fillet-welds are being extended up to S960, in order to integrate the results into the new version of EN 1993-1-12. For this purpose, extensive experimental investigations of the load-carrying capacity are carried out by varying the base material, welding consumable, heat input, plate thickness and weld geometry. With the results obtained and further accompanying investigations, the influences of the varying parameters on the load-carrying capacity of the welded connections will be identified. von Arnim, M.; Eichler, S.; Brätz, O.; Hildebrand, J.; Gericke, A.; Kuhlmann, U.; Bergmann, J.

钢结构焊接混合连接的有效设计理念

由普通强度和高强度钢制成的混合连接可以使作用在它们上的力得到最佳的材料利用。通过减少材料消耗和更小的焊缝几何形状，这带来了生态和经济优势。目前还没有标准强度和高强钢的对接混合连接的规范规则，因此在“钢结构中混合连接的有效设计概念”的研究项目中，需要开发这种连接的设计方法。此外，已经为对接焊和角焊开发的设计概念正在扩展到S960，以便将结果整合到新版本的EN 1993-1-12中。为此，通过改变基材、焊接耗材、热输入、板厚和焊缝几何形状，对承载能力进行了广泛的实验研究。根据得到的结果和进一步的研究，将确定不同参数对焊接连接的承载能力的影响。冯·阿尼姆;为,美国;贝兹娃娃,o .;希尔德布兰,j .;格里克,a;了,美国;伯格曼，j.p.;[李建平，李建平，李建平，等。(2022)基于优化算法的研究与应用。]Stahlbau 91，第10期，660-670页。https://doi.org/10.1002/stab.202200046钢结构焊接混合连接的有效设计概念[D] I, T, R, S, E, C, M, M, E, N, A, T, O, N

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
