Abstract: Abstract In steel bridge girders, longitudinal stiffening is primarily employed to increase the flexural and shear resistance. International design codes recommend the use of longitudinal stiffeners at one-fifth of the girder depth as the optimum… read more here.

DOI: 10.1016/j.tws.2019.106394
Abstract: Abstract In this paper the elastic buckling of longitudinally stiffened plates are discussed in the light of modal deformations. Though in the analysis and design of cold-formed steel members it is a widely used approach… read more here.
