van Es, S.H.J. (author), Gresnigt, A.M. (author), Vasilikis, D (author), Karamanos, SA (author)To investigate the structural behaviour of large-diameter spiral-welded steel tubes under bending, a full scale experimental program has been performed, consisting of thirteen 42-inch diameter, spiral-welded steel tubes with D/t ratios ranging between 65 and 120. Additionally, numerical studies have been conducted, using nonlinear finite element...conference paper 2016

Abspoel, R. (author)In a material economy driven plate girder design, the lever arm between the flanges will increase. This leads to higher stiffness and bending moment resistance, but also to an in-crease of the web slenderness. This means that high strength steels can be used leading to a large reduction of the steel consumption. However, Eurocode 3 [3] restricts...conference paper 2016

Pavlovic, M. (author), Veljkovic, M. (author)The experiment data available on 4-point bending experiments performed in Aus-tralia and Europe on tubular section beams are validated by FEA. Large scattering of available experiment results is investigated by detailed analysis of different geometrical imperfections. Loading set-up is analysed through modelling of welding induced imperfections....conference paper 2016
