Enhanced 3D multifibre beam element accounting for shear and torsion
Résumé
The purpose of this work is to investigate solutions for an enhanced multifibre beam element accounting for non-linear shear and torsion. Higher order interpolations functions are used to avoid any shear locking phenomena and the cross section warping kinematics are extended to non-linear behavior using advanced constitutive laws. The efficiency of the proposed modeling strategies is tested with experimental results of reinforced concrete structural elements subjected to severe loading.
