The calculation of the loadbearing capacity of thin‐walled structures, including trapezoidal sheeting, normally follows the procedures of EN 1993‐1‐3 and similar codes. EN 1993‐1‐4 complements this standard for thin‐walled structures made of stainless steel. Unfortunately, a buckling curve for stiffeners between the plane cross‐section parts of the flanges or the webs is lacking. A finite element analysis was performed in order to obtain a buckling curve for such stiffeners. The finite element model was calibrated based on test results and by recalculating the EN 1993‐1‐3 buckling curve for the stiffeners in trapezoidal sheeting made of non‐alloy structural steel. The results of the research into the loadbearing behaviour of thin‐walled stainless steel trapezoidal sheeting presented here are closing this gap: the proposed addition to the design formulae means it is now possible to carry out a complete calculation of the loadbearing capacity of stainless steel trapezoidal sheeting.

In Germany the stiffness and resistance of diaphragms used for stabilizing members are traditionally calculated according to the Schardt and Strehl approach. Compared with the approach of Bryan and Davies given in the ECCS Recommendations, it does not take into account the flexibility of the connections. This paper shows how to amend Schardt and Strehl’s approach to include this flexibility, leading to more realistic values of diaphragm stiffness. The article also introduces new procedures for the calculation of the resistance, adopted from European standards and recommendations. Finally, both a test and an example taken from the literature are recalculated for comparison.

Der Beitrag behandelt die Bemessungs‐ und Konstruktionsregeln des Eurocode 3 Teil 1‐11 für Zugglieder aus Stahl. Der Beitrag umfasst Regelungen für Zugstäbe und Zugstabsysteme sowie Regelungen für offene und vollverschlossene Spiralseile, Rundlitzenseile, Paralleldrahtlitzen, Paralleldrahtbündel und Litzenbündelseile einschließlich der zugehörigen Endverankerungen, Klemmen und Umlenksättel. Diese Regelungen werden vorgestellt und erläutert. Soweit hilfreich und möglich erfolgt ein Vergleich mit den Regelungen von DIN 18800‐1.Design of tension components according to DIN EN 1993‐1‐11. The paper deals with the design rules of Eurocode 3 part 1‐11 for tension components. The paper covers rules for tension rods and tension rod systems as well as rules for wire ropes, bundles of parallel wires or strands including the corresponding end connectors, clamps and saddles. These rules are introduced and explained. If helpful and possible, a comparison with the rules of DIN 18800‐1 is made.
