Outside Bin Hold-Down Details (2.66" Corrugation)
Outside bin hold-down should be used on all non-stiffened bins/silos. When anchoring the bin, be sure the
vertical seams of the bin/silo align with the U-bolts or single anchor bolts in the foundation. Bin/silos up to
36' diameter and 12 rings tall or shorter may be anchored using either the U-bolt/J-bolt combination or the
single anchor bolt bin/silos 42' and greater in diameter and all 13 rings or taller should be anchored using
the single anchor bolt.
Bins/silos 13 rings and taller require double hold-downs. The sidewall must be field drilled to attach the hold-
down bracket located between the horizontal seams. For the case of 42' and larger bin/silo, no greater than
12 rings tall, double U-bolt/J-bolt combination anchors may be used as an option to the single anchors bolt.
Additional hold-downs are required with this option.
