Gusset Connection Axial

[ac0609]

Hello everyone,

Does anyone have any sort of guidelines/references/examples for this type of connection. I have diagonal angle members bolts to a gusset plate. Gusset plate is welded a W Section.

Thanks in advance.

It doesn't have your exact situation, but has enough that you should be able to work with it.

Our cross frames for bridge girders are very similar, except that instead of a W-beam, the bottom horizontal is an angle. Outside of the standard checks for shear on the bolts and bearing at the bolt holes, we don't really check anything specific to the gusset plate. The bridge design spec has a minimum thickness for the gusset plates (5/16") and limits on the distance between the angles (the unsupported width of the gusset plate) so buckling of the plate is precluded. I suppose without those limits, you'd need to consider plate buckling as a possible failure mode, although if your drawing is to scale, it seems unlikely there'd be any reduction in capacity for that.

There are several critical sections identified for the plate flexure and shear.
