New experimental determination of fatigue strength of tubular truss joints in steel grades up to S690

Alain Nussbaumer, Farshid Zamiri Akhlaghi

In this paper research work on welded butt weld connections between hot-rolled seamless tubes and steel castings are presented. Comparison is made between different weld preparations for the butt welds including different steel grades, repair methods, the ...

Welding simulation of tubular K-joints in steel S690QH

Alain Nussbaumer, Jean-Marie Drezet, Farshid Zamiri Akhlaghi

Residual stress state in planar tubular K-joints, in the chord within the gap region between the two braces, is studied using numerical weld modelling. The motivation comes from past full-scale fatigue tests on tubular trusses made of various steel grades ...

Numerical investigation of welding residual stresses in planar bridge trusses made of CHS steel proﬁles

Alain Nussbaumer, Claire Acevedo, Farshid Zamiri Akhlaghi

The weld-induced residual stresses in a tubular planar K-shaped connection made of construction steel grades S355J2H and S690QH are evaluated using three-dimensional finite element models in thermo-mechanical simulation of welding process. Both lumped sing ...
