Eccentric Loads on Weld Groups
Eccentric Loads on Weld Groups
(OP)
While perusing thru my manual of steel construction-ASD- I came across the Ultimate Strength Method showing me exponential functions for R values. Under what condition is this analysis carried outin light of the fact that when I come across such problem I'll use the more conventional way of calculating weld size based on torsional stresses and polar moment of inertias.

The elastic approach is better suited to hand-written calculations. The assumptions don't really follow the true behavior of the welds but it errs on the conservative side.
If you need to size one weld or a few welds, either method it acceptable. If you have a process or connection that will be replicated many times, you may be able to save the client some money with a less conservative calculation.

Check out weldgroup spreadsheet on www.yakpol.net . It does it both ways, and it's a pretty big difference in capacities calculated by LRFD and ASD.
