Fatigue Design Procedure for Welded Hollow Section Joints: Recommendations of IIW Subcommission XV-E (Woodhead Publishing Series in Welding Format: Paperback. Considering the different effects of different welded joints type on SCF, a variety of fatigue life prediction methods have been proposed for cruciform joints [9][10][11], T-joints [12,13], lap.

  Mismatch effect. The selection of the filler metal in case of the high-strength steels is a very important and complex task. Thin advanced high-strength steel (AHSS) sheets can be successfully welded without filler metal, although in some cases, it may be disadvantageous to the weld quality (cracking phenomena, reaching the strength level).Cited by: 2.

Fatigue Design Procedure for Welded Hollow Section Joints Book • Edited by: A wide range of joint types is covered, the new fatigue design curve for both RHS and CHS is dealt with and detailed values for stress concentration factors are provided. Rectangular hollow sections (RHS) are frequently employed in the constructions of many onshore structures such as cranes and bridges.

During the design of these structures, one of the major concerns is the fatigue behavior under cyclic by:   A novel integral built-up box Y-joint welded to rectangular hollow section braces and concrete-filled square hollow section chord stiffened by perfobond ribs was proposed and studied in fatigue.

Eight specimens, including one control with a hollow chord. Hollow sections are generally either circular-to-circular (CCHS) or rectangular-to-rectangular (RRHS). Structures with circular braces and rectangular chords (CRHS) may have advantages in certain applications, combining a simple joint geometry for fabrication and.

This work presents the results of experimental and numerical research on the fatigue behaviour of T- and X-joints between square hollow sections of which the brace is welded to the face of the chord, without any additional by: or a rectangular hollow section (RHS).

The connections between these hollow section elements are usually made by welding, because this is a simple connection method for tight access. For the case of the welded joints covered in this document, the fatigue phenomenon occurs on the perimeter of the welded connection due to the fatigue stress in File Size: KB.

Special attention was paid to T-joints that consist of the chord member of a single square section and brace members of different kinds of cross sections as Square and Circular Hollow sections. A finite element model was developed for 6 specimens to investigate the influence of some variables such as geometry and β-parameter (ranging from β.

Recent Developments in Welded Hollow Section Joint Recommendations This paper gives a brief review of some of the research recently carried out on hollow section joints, in particular those topics in which the authors are involved. Further, some other research is briefly discussed and references are given for more detailed Size: KB.

N2 - Stress concentration factors (SCF) and fatigue life are two main aspects of studying fatigue behavior of tubular joints based on hot spot stress method. 8 welded CHS-SHS concrete filled T-joints were tested under static loading to determine stress concentration factors at hot spot locations and were also tested under cyclic loading to obtain fatigue life by: 1.

Based on the fatigue testing of butt-welded HSS with a yield stress of MPa, it was found that the fatigue strength of HSS was significantly higher than the fatigue life of conventional steels given by the International Institute of Welding (IIW).

It is interesting to note that different HSSs showed different structural behaviour due to different compositions and manufacturing by: 6.

(author) Van Wingerde. Fatigue is a major cause of failure, particularly in welded structures, reflecting the inherently poor fatigue performance of many welded joints (Fig.1).This emphasises the need for due consideration of potential fatigue failure at the design stage, and for clear design guidance.

In fact, considerable effort has gone into the production or. Fatigue life assessment of welded joints made of circular hollow sections (CHS) with concrete filled (CF) chord member subject to vehicle load is vital in designing of CFCHS arch truss bridge.
