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. The weld model has an elastic-plastic material diagram, and stress peaks are redistributed along the weld length. The relation between the weld length and the bending moment resistance of the joint is shown in Fig. 4.3.3.

Chevron Brace Connection in a braced frame (AISC)
Weld between gusset plate and brace Weld between gusset plate and bottom flange of beam Tension yielding of brace Tension rupture of brace Shear rupture The utilization of this weld is 87%. CBFEM uses the AISC 360-16 provisions of Chapter J to check the weld strength. It can be seen that the weld check utilization is 86.6%.

Verification of IDEA StatiCa calculations for steel connection design (AISC)
(Page 10–11, AISC Manual) Weld Capacity (no eccentricity) (AISC 360-16, Eq. Also, the maximum predicted stress on the beam, column, and weld lines was slightly higher in the ABAQUS model. In case 2, in which load was applied on the weld lines, much better agreement was observed between the two models.

Bearing stiffeners (AISC)
The total weld length is the combined weld length between the web and the stiffeners for each side of each stiffener (i.e., 4 times the length of the weld A continuous weld would have a total length of 138 in. The weld started and ended 2 in. from stiffener's chamfered corners. A comparison of strength versus weld length is presented in Figure 6.

Comparison of IDEA StatiCa Connection to ANSYS
A combined model of weld prepared by Turlier [3] was used. It consists of an inclined shell element simulating the weld. It is not ideal for the comparison because the design weld model is simplified and some stresses in the weld are not assumed. Generally, there was a good agreement between weld stresses. The weld stresses were slightly higher in IDEA StatiCa, meaning that the design is safe.
