Abstract
Finite element models of concrete filled steel tubes subjected to eccentric compression
Incoming article date: 09.10.2022A step-by-step finite element method calculation algorithm of concrete filled steel tubes is provided with an example. A comparison of the finite element calculation results with experimental data, calculations according to Russian (SP266.13 25800.2016) and European standards (Eurocode 4) and the “inverse” numerical-analytical method, which takes into account the actual rigidity of sections, is given as well. The study shows an accuracy of the proposed finite element model using Drucker-Prager model for concrete and the “inverse” numerical-analytical method in comparison with standard calculation methods.
