9.4. Foundation Loads — Grain Bin Series CEW
Important
•
Grain Bin Anchoring: Adequate anchoring is critical to a successful bin installation. The anchoring of
the bin is dependent on local wind loading conditions and forms part of the site specific design
requirements. The anchor bolt details must form part of the site specific foundation design.
•
For stiffened bins the primary anchor bolt locations are through the base plates at each and every
upright location. The anchor bolt design, plus connection details to the base plate, must
accommodate the total shear and uplift loads that can occur due to wind loading at the site in
question.
•
In addition Westeel suggests the use of 1/2" x 3" embedment anchor bolts through the bottom ring
angle to insure bin roundness, for sealing purposes, and for additional localized lateral stability.
