Equivalent Stress in Weld
Equivalent Stress in Weld
(OP)
Hi All,
I have attached a sketch of a welded structure, with 4 gusset plates. The structural analysis program shows the loads in the X, Y and Z direction at the beam intersection. I know it might sound basic stuff for many of you, can anyone advise what is Equivalent Stress for the welding of the gussets? As the welding are in different planes, just need some advice.
Thanks in advance.

Further, it looks like there are (2) weld groups to evaluate. Where is the work point for these concentric forces? I assume it is at the base of the circular post? The picture resembles stiffeners for a column/baseplate, which implies there is some moment at the base of this post. Is the base of the post also welded to the top of one of the wide-flange members?

RE: Equivalent Stress in Weld
If your asking what is the stress in the weld so as to size it. For the weld to the top of the w beams, one aaproach is to assume all the welds take the axial and welds with the gusset plates in the x direction take the loads in the x direction. Add these forces to get your max force in kN/mm and check against the weld capacities in your steel handbook.
Someepoints to note:
1. you havent provided any moments,this connection might not act as a pin. One of the steel r welding design books by blodgette has a section regarding welds stress on welds shapes due to moments.
2. Local yielding of the pipe may be an issue, there are a number of design guides that deal with this.
