Gusset plate weld design
Gusset plate weld design
(OP)
I'm currently looking at a gusset plate with 45 degree diagonals coming into it. My model is giving me diagonal loads of 66 kips coming into the joint. I have a bottom chord load that does not equal the difference of the horizontal components of these two forces. Especially at the center. The maximum compression in the top chord is 180 kips, but there is a 1 kip load in the braces coming into it. At the ends, the diagonal forces are higher and chord force lower. this is expected based on beam design fundamentals. My question is for weld design at the gusset plate. The joint are not in equilibrium it seems if the chord force at the center is 180 kips and very small horiz components of the diagonal members. For the deisgn of the gusset plate weld. Which horizontal force do you use for the weld design connecting the gusset to the chord, the chord compression or sum of the two diagonal loads coming into the joint?

If you modeled it correctly with the vertical members pinned, there should not be contributory lateral shear force, only axial.
