Title:Joint Behavior of a Bolted Railway Bridge During Erection and Service
Author(s):Chesson, Jr., E.
Subject(s):Railway bridges
bolted joints
Abstract:Measurements were made of the movements at connections of a 310 foot railway bridge over a period of three and a half years. The study was initiated during shop-assembly of a truss and was ended after three years of service loadings. As might be expected, substantial relative movements of the bridge joints occurred during erection with the addition of dead load, bracing, and floor systems. The effects of the measured movements on changes in camber are discussed and compared with level readings taken during the three years of traffic. In essence, no service movements were found; no evidence of a marked change in camber was found. These findings suggest that a properly designed structure with properly installed high-strength bolts will not slip under normal service loadings.
