This article provides a detailed investigation of the design concept for full‐locked coil ropes, which are widely used in various applications in the construction sector. The current design concept in the ultimate limit state according to EN 1993‐1‐11 is explained by tracing its development through past standards. A database of breaking load tests is built up and used to evaluate the actual fill and spinning loss factors compared to the standard values. Afterwards, the current design equation and the revised equation of the third draft of prEN 1993‐1‐11 are statistically evaluated with the test‐based design procedure in EN 1990. The investigations reveal that the use of a fill factor is not required and should be omitted, while the spinning loss factor can be approximated by a constant value. The newly proposed equation in prEN 1993‐1‐11 shows improved accuracy in comparison with the current design equation of EN 1993‐1‐11 regarding the calculated partial factors. However, the determined partial factors are based exclusively on tensile tests under laboratory conditions. They could serve as a basis for the development of a new design concept in which project‐specific information such as local bending stresses can be considered individually. This would allow a more precise definition of the safe level of utilisation and thus lead to a more economical use. Further research is required to quantify these factors.

This paper presents a new morphology of a cable-staying system for an under-deck cable-stayed bridge. The computational method proposed in the paper has been derived for a one-strut conventional cable staying system and applied for an unconventional double-level cable-staying system. The paper describes an algorithm for the correct implementation of the interaction between the cable-staying system and the deck. The numerical examples demonstrate that the proposed computational method based on a non-linear analysis of a simply supported and additionally restrained beamcolumn can be used for obtaining deformation response to the considered structure. An analysis of the same problem using finite element (FE) software ANSYS was carried out to present the accuracy of the proposed method. The paper also demonstrates comparison analysis between the conventional and unconventional structural schemes for the under-deck cable-stayed bridge under symmetric and asymmetric loading.Keywords: under-deck cable-stayed bridge, double-level cable-staying system, non-linear analysis, computational method, beam-column, elastic restraint, structural response.

Es ist bekannt, dass das Fertigungsverfahren von Zugstäben mit Endgewinden einen großen Einfluss auf die Ermüdungsfestigkeit hat. Der Einfluss des Feuerverzinkens auf die Ermüdungsfestigkeit ist jedoch weniger bekannt. Es werden die Ergebnisse von Ermüdungsversuchen an geschnittenen, gerollten, gerollt feuerverzinkten und feuerverzinkt gerollten Zugstangen mit Endgewinden präsentiert und diskutiert. Fatigue of tension rods with hot dipped galvanized threads.It is known that the manufacturing process of tension rods with threads has a great influence on the fatigue strength. The impact of hot-dip galvanized tension rods on the fatigue strength is less well known. The results of fatigue tests of cut, rolled, rolled hot dipped galvanized and hot dipped galvanized rolled threads will be presented and discussed.
