Weld requirement for plated girder
Weld requirement for plated girder
(OP)
Good Day Folks
I am designing a plate girder. I also need to specify weld sizes for web to flange welds.
My question is, how do I calculate the weld requirement, I need to first know the shear stress flowing between flange and web, correct? Can I assume this to be the same as maximum stress in member, ie at top or bottom edge of the section? Then calculate a weld size with the equivalent longitudinal capacity?
What is the simplest way to do this?
Thanks

RE: Weld requirement for plated girder
I started writing this spreadsheet last year when I was designing a prefabricated plate girder. From memory, the weld between the web plate and the flange plate was an 8mm continuous fillet weld structural purpose. If you are using english units, this would be equivalent to a weld 1/3" throat thickness.
The second tab of the spreadsheet has an excerpt from the blodgett text. The stress in the weld isn't directly proportional to the 'stress in the flange' but the 'change in stress in the flange' which is a result of shear in the web.
