Abstract: Aerodynamic admittance is a key parameter affecting the analysis accuracy of the bridge buffeting response. However, few articles have covered the issue of the wide-body flat box girder with much smaller depth-width ratio (such as 1/12 studied in this paper). Therefore, to explore the real buffeting force of the wide-body flat box girder, experiments of the static force coefficients a...

To improve the stability of the magnet-girder assemblies in the ESRF storage ring, vibration investigations have been carried out for in situ magnet-girder assemblies and a prototype. Characterisation tests were performed : operating response measurements, static stiffness measurements, modal testing. A finite element modelling (FEM) is being carried out for the prototype assembly. First result...

Modal properties are recognized as indicators reflecting structural condition in health monitoring (SHM). However, changing environmental and operational variables (EOVs) cause variability the identified modal parameters subsequently obscure damage effects. To address issue caused by EOV-related variability, this study investigated of frequencies long-term SHM a steel plate-girder bridge. A Bay...

This study aims to provide an effective method the behavior of a steel–concrete composite deck. First, structural characteristics deck and challenges arising in computational analysis structure using general software are described. Then, LPGE element that combines plate girder into one conveniently construct model with high computation efficiency is proposed. Based on principle multivariate fie...
