Optimisation of compressed stiffened flanges in bridge box girder cross-section
Abstract:Optimization of compressed stiffened flanges in bridge box girder cross section Due to bending, flanges of steel box girder cross sections act as compression plates and require stiffeners. Using stability evidence from EN 1993-1-5, a parametric study was performed for six different types of stiffeners. The obtained diagrams show design buckling resistance stress for various plate width and thickness values, and the type and number of stiffeners. Furthermore, an optimization process was performed to find the mo… Show more
