A small correction: HSS is NOT equal to weld strength. However, in case of fatigue, HSS can be used to determine SCF and using appropriate S-N Curve, you may obtain the number of cycles to failure. Apologize for that mistake.
Well, you need to model the weld either as a solid or shell element. (Chalmers also recommends increased thickness). Also you need to consider the following:
1. Weld residual stresses caused by welding.
2. Weld toe dimensions as recommended by AWS specifications for groove welds.
3...

I am trying to investigate the variation of weld SCF with the ratio of chord to brace diameters in tubular joints. I prepared a model on ANSYS but got stuck on how to model the weld to satisfy the following:
1. Create points that represent those recommended for extrapolation...
