General Order 95
Section IV
Strength Requirements for All Classes of Lines
| 48.1 | Wood | ||
| A. | Natural Wood (Non Laminate) | ||
| (1) | Poles | ||
| The required strength for natural wood poles of various species meeting the requirements of ANSI O5.1 2008 shall be derived in conjunction with the safety factors in Rule 44 and the designated fiber strength specified in ANSI 05.1 2008. Table 5 lists some of the values of fiber strength specified in ANSI 05.1 2008. | |||
| (2) | Sawn Wood Structural Members | ||
|
The required strength for sawn wood structural members, such as crossarms and braces, meeting the requirements of ANSI O5.3 2008 shall be derived in conjunction with the safety factors in Rule 44 and the designated fiber strength specified in ANSI O5.3 2008. Multiply the given allowable stress values by 0.55 for sawn wood where the loading being considered is a long-time loading (i.e., continuous load for one year or more). |
|||
| B. | Laminated Wood | ||
| The required strength for laminated wood poles and other structural members, such as crossarms, meeting the requirements of ANSI O5.2 2006 shall be derived in conjunction with the safety factors in Rule 44 and the designated strength specified in ANSI O5.2 2006. | |||
