The gusset plate
project provided essential knowledge that led to the rapid development of national safety standards that will help prevent other potential gusset plate
bridge design failures.
Failure modes for gusset plate
connections are local buckling of gusset plate
and purlins, and elongation of boltholes.
As a result of a design error decades before, the gusset plates
in the bridge were about half as thick as they should have been, Ocel said.
The specimens were divided into four groups according to types of gusset plates
as follows: 1, the gusset plate
with a thickness of 12 mm; 2, the gusset plate
with a thickness of 18 mm; 3, the gusset plate
with a circular hole at the center; and 4, the gusset plate
with three pairs of solid square ribs.
Designing joints with gusset plates

The main finite element used in the model is SHELL181 for the studs, tracks, gusset plates
, hold-downs, and braces.
Differences in performance of the short and long gusset plates
became more obvious in the glued joints.
The main difference between the second modified design and the first was the extension of the gusset plate
to the outer edge of the wing plate.
