Loads unfortunately are a completely different matter.

You can switch to the 222-G strength check simply by selecting it in General/General Data. Getting Started With 222-G The geometry of a TOWER or PLS-POLE model will not require any changes to be used with 222-G (except for bolts in TOWER see below). In fact, the 222-F support in TOWER and PLS-POLE has improved in version 7 as described in the Notes on Version 7 for Telecommunications Users section below (which was taken from the Loading Methods Introduced in Version 7 of TOWER and PLS-POLE technical note). In addition, you will continue to be able to select 222-F as a strength check and a loading option. EIA-G-14 and EIA-G-15 in the TOWER manual) Copyright Power Line Systems, IncĢ February 2008, TOWER version 10.01: Now exactly implement this section rather than using simpler, but more conservative ASCE method for block shear Now calculate A net = 0.75(A eff - h x t x n h ) rather than the more conservative A net = (0.75 x A eff ) - (h x t x n h ) which was introduced in July 2007 with Addendum 1 Notes for Users of 222-F Models made in previous versions that used 222-F will open in the current version and produce the same results they did before.

EIA-G-17 and EIA-G-18 in the TOWER manual) The 0.75 factor has been changed to 0.80 for R DIS, but R BSH still uses 0.80 (Eqns. EIA-G-7 and EIA-G-8 in the TOWER manual) Resistance factor for compression changed from 0.85 to One quarter of the bolt diameter is now added to dist1 and dist2 used for calculating R DIS (Eqns. Revisions July 2007: Addendum 1 incorporated into TOWER and PLS-POLE version 8.20 with the following changes: Renamed design check to 'ANSI/TIA 222-G-1' to make it clear that Addendum 1 is included : Updated exposure category extent from 10 to 20 times structure height : Warnings that refer to this section now print the Grf should be 1.1 to : TOWER: K a = min(0.6,(1-є)) now only applied when subcritical (so K a = 0.6 for supercritical wind case may change to K a = 1) : TOWER: K a is applied by the program so should not also be applied in through as per Note 3 in : The allowable horizontal displacement is now 3% of structure height instead of 5% in the Service Loads Check Table 2-2: TOWER does not automate the special case of 'latticed structures with other than triangular or rectangular cross sections TOWER never suffered from this typo Resistance factor for compression changed from 0.85 to 0.90 (Eqns. This document will briefly explain how TOWER and PLS-POLE can be used to meet some of the requirements of 222-G. 222-G represents an enormous change from 222-F in both the loading and strength philosophies employed. Whitney Way, Suite 160 Madison, Wisconsin 53705, USA Phone No: (608) Fax No: (608) URL: Using ANSI/TIA 222-G in TOWER and PLS-POLE Introduction TOWER and PLS-POLE have been tracking the evolution of ANSI/TIA 222-G for some years.
