Abstract The relatively new fibre optic measurement technique: distributed sensing (DFOS) is provided to control strains and displacements, used in the structural health monitoring of a decommissioned wind turbine blade (WTB) bridge girder. DFOS system characterized by following features: accurate, reliable continuous strain measurements, possibility assessing shape detection local damages, hig...

Laboratory tests on relatively small plywood box beams are described. The results suggest that stability of the plywood webs of more realistically sized box beams is not ensured by the rules in timber design codes. A literature search failed to produce sufficient relevant material on plywood panel stability. Hence, the decision to proceed with the theoretical program whose preliminary steps are...

In order to study the distribution of stress and deformation variable cross-section continuous box girder bridge, in this paper, finite element method is used establish model bridge. Considering layout lane load, combination working conditions calculated, bridge are analysed. The results show that maximum generally occurs at beam span middle section or support, sometimes value vehicle load poin...

Abstract In general, a web of the steel box girder is designed as an independent. However, in actual behaviour, since and flange behave couple, considered to have higher bending buckling strength than standard due restraint by flanges. Therefore, horizontal stiffeners for might be omitted. this study, focusing on effect coupled behaviour girder, FE analyses were carried out model with different...
