Résumé / Abstract
The present research focuses on the numerical modelling of structures using the multiber beam element method. A formulation to account for shear warping is developed. The local warping degrees of freedom are computed along with the global beam degrees of freedom by satisfying the structure equilibrium. In
the case of pure torsion, the evolution of the warping shape only depends on the concrete damage state. The comparison of numerical and experimental torque-twist curves ascertains the importance of including torsional warping in the formulation. Ongoing work tests the numerical behaviour of structural elements
subject to transverse shear warping.
