CBFEM Weld Model: Validation and Verification
Figure 1: Constraint between mesh nodes (butt weld) Figure 2: Constraint between weld element and mesh nodes (fillet weld) The aim of design weld models The resistances of the regular welds, welds to unstiffened flange, long welds, and multi-oriented weld groups were investigated to select parameters of to the weld axis and for the multi-oriented weld group.

Bolted portal frame eaves moment connection
Fillet weld The weld is closed around the whole cross-section of the beam. The thickness of the weld on the flanges can differ from the thickness of the weld on the web. Design of the weld is done according to EN 1993-1-8:2005, Cl. 4.5.3.2(6).

Circular hollow sections
Failure mode method In this chapter, component-based finite element method (CBFEM) for design of uniplanar welded Circular Hollow Sections (CHS) is verified In the following studies, the welds are designed according to EN 1993‑1‑8:2006 not to be the weakest components in the joint. The design resistance of the axially loaded welded CHS joint is: for T and Y joint \[ N_{1,Rd} = C_f \frac{f_{y0} t_0^2}{\sin{\theta_1}} (2.6+17.7 \beta

Plate to circular hollow section
Failure mode method Uniplanar welded plate to circular hollow sections T-joints predicted by CBFEM are verified to FMM in this chapter. The welds, designed according to EN 1993‑1‑8:2006, are not the weakest components in the joint. The design resistance of the axially loaded welded plate to CHS joint is: T joint Transverse \[ N_{1,Rd} = 2.5 C_f f_{y0} t_0^2 (1+3 \beta^2) \gamma^{0.35

Rectangular hollow sections
Square hollow sections (SHS) brace is welded directly onto an RHS chord without the use of reinforcing plates. The welds designed according to EN 1993-1-8:2005 are not the weakest components in the joint. Range of validity CBFEM was verified for typical T, Y X, and K-joints with gap of the welded rectangular hollow sections.

Column base – Open section column in bending to strong axis
components are examined: column flange and web in compression, concrete in compression including grout, base plate in bending, anchors in tension, and welds Welds were the same around the whole column section with sufficient throat thickness in order not to be the critical component. One parameter was changed while the others were held constant at the middle value.
