Fatigue behaviour and detailing of slotted tubular …1.1 Detail category (value at 2 million cycles) In slotted tubular connections, the tube may either be a circular (CHS) or a rectangular (RHS) hollow sec-tion, as shown in figure 1. Regarding the connection, its fatigue behaviour can be influenced by: the de-tailing of the welds between the tube and the plate,

What is flange bolted joints observed?

Some specific aspects about the behaviour of flange bolted joints observed have been observed during the tests: - The initial stiffness of the joints is very high, and the linear branch observed when unloading the specimens in the non-linear domain is not parallel to the initial branch (Figs.11 and 12).See all results for this questionWhat is fatigue design?Most fatigue design rules present a series of S-N curves for particular weld details ( Fig.2 ), where S is the nominal stress range adjacent to the weld detail. These are derived from constant amplitude fatigue test data, obtained from welded specimens, by statistical analysis [16] .See all results for this questionUS7513534B2 - Fatigue-resistant threaded component for a fatigue behaviour and detailing of slotted tubularA fatigue-resistant threaded element for a threaded tubular connection. A portion of threads of the threaded element have a helical groove opening into the threaded crest. A groove is formed in all or a portion of the threads of one or both end zones, namely the first engaged thread zone and the last engaged thread zone, and it is optionally formed in the threads of the medial thread zone.

Significance of weld profile on the fatigue lives of fatigue behaviour and detailing of slotted tubular

This paper describes the fatigue behavior of monopod tubular joints in air and cold ocean environments. The test program includes testing of seven joints under constant amplitude and pseudo-random loadings in as-welded and weld toe ground conditions. The corrosion tests were carried out in natural seawater at 0/sup 0/C.Some results are removed in response to a notice of local law requirement.

Nussbaumer Experimental and theoretical development for Fatigue design rules for welded structures (January 2000 fatigue behaviour and detailing of slotted tubularThis paper outlines the basis of current fatigue design rules for welded structures. Covers how they are applied in different specifications, including consideration of residual stresses, size effect, material, welding process and environment. Areas needing further research are highlighted. Hot spot stress approach to keep pace with the increasing use of FEA is discussed.Fatigue behaviour of CHS tubular bracings in steel bridgesThe structural solution for cross girder bracings or box girder diaphragms in steel bridges is often made with tubular elements, specially efficient if compression is required for structural behaviour. The connection between the tubular elements and the girder plates is usually made with a gusset welded on a slit in the tube. The weld between the gusset and the tube at the end of the slit is a fatigue behaviour and detailing of slotted tubularCited by: 5Publish Year: 2017Author: Claudio Baptista, Saad Kannuna, José Oliveira Pedro, Alain Nussbaumer
