Experimental verification of a beam element for thin-walled beams with torsion, distortion, and shear lag Cambronero Barrientos, Francisco Aragón Torre, Ángel Martínez Martínez, José Antonio Aragón Torre, Guillermo Thin-walled beams Warping Torsion Distortion Shear lag Finite-element method Box girder Bridge deck Experimental verification Beam-type elements based on the theories of Euler–Bernoulli, Timoshenko, and Vlasov are widely used in civil engineering. However, shell and solid finite elements are often used when the effects on normal stresses of either shear deformation or distortion are considered important. Numerically validated in an earlier study with finite element models for shell-type structures, the same one-dimensional finite element model is further developed in this study with a low number of degrees of freedom per node that includes all the structural mechanisms without using 3D finite element models. Laboratory testing of an instrumented steel box girder is conducted, to improve validation of the goodness of fit of the finite element model with real structural behavior. 2024-02-12T11:37:22Z 2024-02-12T11:37:22Z 2022-06 info:eu-repo/semantics/article 0141-0296 http://hdl.handle.net/10259/8675 10.1016/j.engstruct.2022.114249 eng Engineering Structures. 2022, V. 261, 114249 https://doi.org/10.1016/j.engstruct.2022.114249 http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Attribution-NonCommercial-NoDerivatives 4.0 Internacional Elsevier
