Effects of heat input on the mechanical properties of butt-welded high and ultra-high strength steels
(Elsevier, 2019-08-09)
In this study, the mechanical properties of butt-welded thin plates made of S700, S960 and S1100 steels under various heat inputs (HI) are investigated. The gas metal arc welding (GMAW) process with two different levels ...
Weldability of cold-formed high strength and ultra-high strength steels
(Elsevier, 2019-03-22)
Hollow sections and cold-formed steels have a key role in modern structures and machinery. In addition, to benefit from full potentials of cold-formed steels, it is usually required to weld them to other steel parts of ...
Distortional buckling of X‐joints made of square hollow cross‐section beams: theoretical energy‐based model
(Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co. KG, Berlin, 2019-01-21)
Current design codes do not consider distortional buckling failure modes, which can occur in the chord member of a tubular X‐joint loaded axially by brace members. In this study the critical load for distortional buckling ...
Bond characteristics between high/ultra-high strength steel and ultra-high modulus CFRP laminates
(Elsevier, 2019-12-24)
With the increasing applications of high and ultra-high strength steel (HSS/UHSS) in engineering structures, there is a need to address rehabilitation and strengthening of such steel grades using carbon fibre reinforced ...
Fatigue strength assessment of ultra-high-strength steel fillet weld joints using 4R method
(Elsevier, 2019-11-30)
A fatigue analysis on experimentally tested transverse fillet-welded non-load-carrying T- and X-joints made of S960 and S1100 ultra-high-strength steel was carried out in the present study. The test data consisted of welded ...
Fatigue strength capacity of load-carrying fillet welds on ultra-high-strength steel plates subjected to out-of-plane bending
(Elsevier, 2019-06-12)
Weld root fatigue strength capacity is an important design criterion in load-carrying (LC) fillet welded joints subjected to cyclic loads. This paper elaborates on the weld root fatigue strength capacity of fillet welded ...
