1. [TowerTalk] stretched EHS (score: 1): Author: Steve Maki <lists@oakcom.org>; Date: Wed, 12 Oct 2022 14:29:45 -0400; I have a question for the materials crew here. I'm writing up a job report. Our crew went to a site where a huge tree had fallen on the two lower guys of a 360' tower. We carefully (well as carefully; /archives//html/Towertalk/2022-10/msg00083.html (7,113 bytes)

Re: [TowerTalk] stretched EHS (score: 1): Author: Steve Maki <lists@oakcom.org>; Date: Wed, 12 Oct 2022 18:24:39 -0400; I should have mentioned that the guy wire in question is ~330' long, and elongated by ~6". I know - it's amazing that it didn't break. -Steve K8LX Our crew went to a site where a huge tree had fallen; /archives//html/Towertalk/2022-10/msg00084.html (7,670 bytes)
3. Re: [TowerTalk] stretched EHS (score: 1): Author: "Lux, Jim" <jim@luxfamily.com>; Date: Wed, 12 Oct 2022 16:04:34 -0700; It's a fair ways from yield (fy) to failure (fu) for steel. I don't know the alloy here, but looking over a table, it looks like fu is 10% higher than fy for most of the "high strength" steels.

5. Re: [TowerTalk] stretched EHS (score: 1): Author: Al Kozakiewicz <akozak@hourglass.com>; Date: Thu, 13 Oct 2022 00:08:38 +0000; Caveat - not an expert here. Steel wire is often stretched to increase its tensile strength at the expense of elasticity. I do not know if EHS is normally prestressed. If it is, then you would probab; /archives//html/Towertalk/2022-10/msg00087.html (11,448 bytes)
6. Re: [TowerTalk] stretched EHS (score: 1): Author: Grant Saviers <grants2@pacbell.net>; Date: Thu, 13 Oct 2022 06:08:20 -0700; Steve, I got to thinking more about your question - am wondering what you decided. I assume you measured the small (0.2%) change in length when resetting the guy to the initial specified tension. Tha; /archives//html/Towertalk/2022-10/msg00089.html (11,265 bytes)
7. Re: [TowerTalk] stretched EHS (score: 1): Author: Steve Maki <lists@oakcom.org>; Date: Thu, 13 Oct 2022 09:57:48 -0400; Grant, Thanks for thinking about this, really appreciate it. We did not notice a *bend* in the wire while it was loose - however, our main concern was getting all the guys back in service and getting; /archives//html/Towertalk/2022-10/msg00090.html (12,765 bytes)
8. Re: [TowerTalk] stretched EHS (score: 1): Author: <john@kk9a.com>; Date: Thu, 13 Oct 2022 13:17:46 -0400; That is a very minimal stretch if it was evenly over the whole EHS cable, I assume that you checked to see that it did not just pull out of the termination. Perhaps the EHS stretched from a single sp; /archives//html/Towertalk/2022-10/msg00091.html (8,787 bytes)

Re: [TowerTalk] stretched EHS (score: 1): Author: Steve Maki <lists@oakcom.org>; Date: Thu, 13 Oct 2022 15:36:31 -0400; You're right that the difference between a few inches stretch over the whole length and the same stretch over a short length is vast. There was no grip slippage. The tower is now perfectly straight r; /archives//html/Towertalk/2022-10/msg00095.html (10,526 bytes)
