Like guyed structures, framed structures are typically analyzed as a
system using three-dimensional structural analysis software. The struc-
ture designer should determine the size, orientation, and connection
details of all members in the frame.
Combined Structures
Structures may be designed as a combination of cantilevered, guyed,
or framed structures. Examples include a single-pole structure guyed
below the bottom conductor, an H-frame structure cantilevered above the
crossarm, and an H-frame structure guyed at the bottom of the X-brace.
The cantilever nature in the longitudinal direction of a braced H-frame
structure can be changed with the addition of guys in this direction.
Fig. 1-7 shows a combined structure that resist some loads through guy
wires.
