INITIAL CONSIDERATIONS - Prestressed Concrete Transmission Pole Structures - page 20

Specifi c grounding requirements should be clearly specifi ed by

Purchaser.
The Manufacturer should provide an electrical bond between the pole's
internal steel reinforcing prestressed cage and the pole ground.

TESTING

Full-scale structure testing may be necessary depending on special load
cases, new design methodologies, legal obligations, or requirements of the
Purchaser or Manufacturer.
When structure load testing is required, the Manufacturer should be
provided with the type and height of structure to be tested and the load
cases to be examined.
Two types of testing are used to determine the fl exural behavior and
capacity of the poles under static loading: pole testing and structure
testing. Pole testing is used to verify the design and the quality of the
production of the poles. In this test, poles normally are tested in the hori-
zontal position (see Fig. 2-5). The test will verify the cracking moment,
ultimate capacity, and defl ection of the pole. Structure testing involves
