The first resists vertical loads; the second resists
vertical and lateral loads, Frame ties will always
be required to resist lateral and uplift forces, If the
manufactured home is designed for over-the-top
ties they can be used in conjunction with frame
ties,
Ties are made of rust-resistant steel cable or
straps which fasten the home to anchors em-
bedded in the ground, In combination over-the-top
and frame ties. the cable or strap is secured to
the ground anchor with a yoke-type fastener and
a tensioning device, or with clamps and turn-
buckles as shown in Figure 3,30,

Figure 3.30 Tie Components

In frame ties, the strap is secured to the ground
anchor and manufactured home I-beam as shown
in Figure 3.31,

Figure 3.31 Tie Components

As indicated previously, ties are just one com-
ponent of a two component anchoring system, An-
chprs are the component set in the ground to
which ties are connected, This effectively transfers
wind loads, both lateral and uplift, to the ground,
As shown in Figure 3,32, these loads can be
significant enough to dislodge anchors,

Figure 3.32 Failed Anchors

There are several types of ground anchors
which can be used, including screw augers, ex-
panding ahchors, slab anchors, and concrete
deadmenas shown in Figures 3,33 to 3,35,
