Pole framing or post-frame construction[1] (pole building framing, pole building, pole barn) is a simplified building technique that is an alternative to the labor-intensive traditional timber framing technique. It uses large poles or posts buried in the ground or on a foundation to provide the vertical structural support, along with girts to ...
size 2 from 6.5 feet (2.0 m) to 11 feet (3.4 m), size 3 from 8 feet (2.4 m) to 13 feet (4.0 m), size 4 from 10.5 feet (3.2 m) to 16 feet (4.9 m). The safe load for each prop depends upon the size and extension of the prop. Size 1, 2 and 3 props can take about 34 kN unextended, dropping progressively to less than half of that when fully extended.
In 1878 Kenyon convinced his chief to make the necessary hole in the building and install the pole, after agreeing to pay for any necessary maintenance.

Overhead lines or overhead wires are used to transmit electrical energy to trams, trolleybuses or trains. Overhead line is designed on the principle of one or more overhead wires situated over rail tracks. Feeder stations at regular intervals along the overhead line supply power from the high-voltage grid.
Traditional timber framing is the method of creating framed structures of heavy timber jointed together with various joints, commonly and originally with lap jointing, and then later pegged mortise and tenon joints. Diagonal bracing is used to prevent "racking", or movement of structural vertical beams or posts. [ 14 ]
