Abstract
Summarises an investigation into the build-up of residual stresses during the construction of the Cleddau steel box girder bridge. Strain measurements were taken on selected plate panels and stiffeners at various stages of fabrication, site assembly and erection. The Note describes the different forms of residual stress and their relevance to box girder construction. A complex pattern of residual stress build-up was found. Stresses in individual plate panels and stiffeners were often substantially higher than average stress levels across a section. This has been put down to the influence of mechanisms of weld shrinkage other than those normally considered, and to the influence of other construction processes, particularly the methods of obtaining good fit-up.
