Fillet weld in lap joint
The weld is designed according to EN 1993-1-8:2005. The weld configurations are T for transverse, P for parallel weld, and TP for a combination of both; see the geometry in Fig. 4.1.2. The weld resistance is always the governing failure mode. The weld throat thickness is 3 mm.

Fillet weld in fin plate joint
The plate/weld is loaded by normal and shear force and bending moment. Analytical model The fillet weld is the only component examined in the study. Weld normal resistance calculation Where: \(a\) - weld throat thickness \(N\) - the normal force acting on the beam \(l\) - total weld length \(\beta The weld model has an elastic-plastic material diagram, and stress peaks are redistributed along the weld length.

Fillet weld in angle plate joint
Total resistance calculated as sum of top and bottom weld resistances Where: \(a\) - weld throat thickness \(V\) - shear force acting on beam \(l = 2 The weld model has an elastic-plastic material diagram, and stress peaks are redistributed along the weld length. Two parameters are studied: the length of the weld and the angle section. Fig 4.2.2 shows the s ensitivity study of bottom weld length.
