3. DESIGN
3.1 Design Criteria
When moment curves, shear, torsion, and axial components are fur-
nished by the Purchaser, those values shall be the fi nal ultimate conditions
for structure design purposes, including any secondary moments (P-Delta
effect) due to the structure defl ection.
Otherwise, the pole designs shall be prepared from load trees or wire
data, confi guration drawings, and design load cases furnished by the
Purchaser or the Purchaser's consulting engineer. The pole's ultimate
capacity shall be capable of withstanding all specifi ed loads, including the
secondary moments.
The load information provided by the transportation and distribution
(T&D) Purchaser will include wind and/or ice criteria on the wires.
The Manufacturer will apply the specifi ed load conditions to the
structure and appurtenances (platforms, fi xtures, antennas, etc.), when
applicable.
