At present, the research on application effect of steel box girder bridges is still only in qualitative analysis link, and calculation index weights greatly affected by personal subjective factors, quantitative evaluation has not been achieved. In this paper, we proposes a combination objective combined weighting fuzzy model, which avoids unreasonable problem single method determining weight co...

In construction industry, cold-formed steel sections become more pertinent in place of hot-rolled members. The design guides for CFS are inadequate and hence it is substantial to investigate their governing behaviours as material failure structural instability (buckling). This study aims analyse how the buckling face-to-face built-up box short columns administrated by application end plates wit...

An investigation on the flutter derivative prediction of flat steel box girders is carried out based CFD simulations. Firstly, by taking girder section Qingshan Yangtze River Bridge as basic and considering its width height design variables cross-section shape, domain shape defined controlling possible variation range variables. A small number cross-sections are selected for calculation aerodyn...
