Hi - I've reverted you. We don't use self-published sources or forums for our articles. The forum link was just an anonymous author writing on a WP:FRINGE forum. The website was that of a civil engineer who has published his own book through his company. Please read WP:VERIFY and then WP:RS. Thanks. Doug Weller talk 09:19, 1 March 2016 (UTC)
