Figure 2I Single Anchor Bolt
Figure 2J U-Bolt/J-Bolt Combination
Outside bin hold-downs 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.
