Analysis of Welded Tubular Connections Using Continuum Damage Mechanics

Effects of truss behaviour on critical temperatures of welded steel tubular truss members exposed to uniform fire

“…In the case of modelling using shell elements, quadratic wedge solid elements (C3D15) instead of shell elements were used for the weld to allow accurate meshing of the weld geometry [18]. At the weld-tubular section interface, the brace and chord members were tied with the weld elements using the ABAQUS ''tie'' function with surface to surface contact.…”

An experimental and finite element study of the non-linear force-displacement characteristics of tubular YT-joints under combined axial loading

“…1) are statically tested to failure under a range of different monotonic, proportionally applied T-and Y-brace axial force combinations and the non-linear force±displacement responses of the brace ends are measured. Although the non-linear force±displacement and/or moment±rotation responses of steel tubular joints have previously been measured experimentally and calculated using FE analyses (see, for example, references [17] and [20] to [23]), this has generally only been in the context of static strength determination and not, as in the present case, for the systematic study of the non-linear joint behaviour as a function of applied T-or Y-brace loading path. Different geometrically and materially non-linear FE modelling approaches, including both three-dimensional brick and shell element models, for the simulation of the YT-joint non-linear elastic±plastic behaviour are investigated via comparison with the experimental results.…”
