RE: Eccentric Loads on Welds

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Have often thought about that but the hassle and cost doesn't seem to make it worth doing ... also educating the fabricator in such "sophisticated" logistics is a daunting task ... :)

"apart from the heat effect" - Can you temper the welded part? Will help your beginning index.

Treat the welds as line elements and calculate section modulus for. Section properties of various weld groups can be found in handbooks: circular, two vertical lines, 2 horizontal lines etc..

Calculate normal and shear forces, then translate into how the code checks the combination. Here older codes checked transverse and longitudinal actions on different shear planes in the weld, current codes largely ignore and check against a single resistance.
