3. Angle brackets
Angle brackets and gussets are structural units that are
frequently used in assembling critical structural components.
These are L shaped fasteners used to join two surfaces together
to create a 90-degree angle or conventional corner.
Functionality of gussets in an angle bracket
Provide a high strength connection
between profiles. Gussets are used to
attach profiles at 90° angles without
any additional fasteners

6. DESIGN METHODOLOGY
DRAFTING OF
L Bracket
2D draft has been
obtained in
Solidworks V 2020
to achieve the
right kind of
angle brackets
for the
design

7. Modelling
Step 1: Extrude the L shape with the given
size. Then Make holes using hole wizard
Step 2: Make fillet radius to achieve right flush
Step 3: Create plane at the given dimensions to
sketch and extrude the ribs “gussets”
Step 4: Create a wall on the plane which is to me
clamped using bolts for a practical simulation.

8. Step 1: Adding Loads & Fixtures
Step 2: Apply load (1000N)
and connector force(axial 30N)
and contact surface
Step 3:Create mesh(4.55574
mm) Step 4: Run the study

10. Study without Gusset
Redesign: Cut the gusset by extruding a hole
after sketching
Rerun the study: With the same constraints
we have gathered the study.
Factor of Safety= 3.6
Max Stress=1.734e^08 N/m^2

11. Results & Discussion
In regards to the analytical study, the following basis of designs are considered:
● The applied loading ‘P’ assumed uniformly distributed
● Yielding and ultimate stresses are used as characteristic values.
● Preferable FOS=4 to 6
● Heel-toe load
The portion of the bottom leg is not important for this check because it is
assumed to react the heel-toe load. This produces the counter acting moment required to
balance the applied moment
● The characteristic yielding moment is calculated from a net cross section by reducing the
width by the net sum of the hole diameters(EOTA report)
● The classic formula for determining the bending stress in a member is: f/y=M/ I

13. Considering an Angle bracket with a rib subjected
to a lifting force or to a shear force in the direction of the
Wall
The force is transferred from the wall to the vertical
leg by lateral force in the nails. The axial force in the
nails causes bending moments in the leg.
Structural Analysis of such configurations:
Welded gussets are a suitable choice to achieve added
strength and rigidity. Welding also means extra manufacturing cost
Further critiquing this design to optimise, simple
adjustments can make major impact.
This can analytically be done by considering
design parameters using Taguchi method before manufacturing.
An example where only bending and machining would
be involved in manufacturing gussetted angle bracket is-

14. The workstation will experience a load applied to its unsupported end. As a
result, there will be a cantilever force experienced at the supported end of the
station.
If length is increased and force increased the workpiece will break.
To help counter such cases a gusset or angle plate can be installed to distribute the
load.
The factors to consider are as follows:
A tight perpendicular tolerance and a proper fit to avoid failures.
Such pieces are machined or casted. This design is opted more often as it is added
to reinforce more mounting hole option and offer large surface area. Although just a
casted ribs are light weighed. The structural integrity of such design is more reliable.
