Warping effect in a multifiber beam model for nonlinear analysis of reinforced concrete structures under torsion

Abstract : A procedure is developed to account for torsional warping in the computation of fiber deformations in multifiber beam element models. The theoretical and numerical formulations to compute the cross section warping are presented and validated against axial displacements in a 3D finite element model of a column. The global nonlinear response of a column under torsion is then computed using a multifiber beam model. Differences in global and local behavior between both models with and without warping show the importance of warping effect both in linear and nonlinear behavior.
