Stability of plywood webs of box girder beams

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...

Drying and Cracking Effects in Box-girder Bridge Segment

This paper deals with the effect of drying as a moisture diffusion process in a segment of a typical box-girder bridge. Pore relative humidity distributions throughout the cross sections of the plates of the girder are calculated from the diffusion equation, taking its nonlinearity and aging into account. The effect of creep with aging on the stresses produced by drying shrinkage is taken into ...

Aerodynamic Admittance Research on Wide-body Flat Steel Box Girder

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...

design optimization of box type girder of an overhead crane

double bridge girder overhead cranes are used for heavy duty applications in theindustry. in this paper a detailed parametric design optimization of the main girder of box type isperformed for a 150ton capacity and 32m long span crane, after its basic design using availabledesign rules. design optimization is performed using detailed 3d finite element analysis bychanging the number, shape and l...
