A tower that is 3 feet across has 1/3 the load of a tower that is 1 foot across. A 400 foot tower that's 10 feet across with 40 bolts isn't putting a huge load o; /archives//html/Towertalk/2018-03/msg00198.html (9,200 bytes)

Obviously 10 bolts will have 10x the strength of one, including pull out strength. Most SS towers are designed for fewer large bolts rather than many small bolts.

(score: 1): Author: Mike Fahmie via TowerTalk <towertalk@contesting.com>; Date: Sat, 24 Mar 2018 23:11:39 +0000 (UTC); No, the pull out strength will depend on how far apart the anchors are. Closely spaced anchors will compromise pull out strength. Optimum spacing will depend on anchor depth.-Mike WA6ZTY From: Stev; /archives//html/Towertalk/2018-03/msg00205.html (10,595 bytes)

(score: 1): Author: Steve Maki <lists@oakcom.org>; Date: Sat, 24 Mar 2018 20:21:10 -0400; Yep, because closely spaced bolts can more easily pull out a *chunk* of concrete containing all the bolts than widely spaced ones.
