“…However, the behavior of flanged beams under torsion is more complicated when compared with rectangular beams and highly depends on the cross section shape, on the relative dimensions of the components of the cross section and also on the detailing of the reinforcement (both longitudinal and transverse) [8][9][10][11]. For the case of L-shaped beams, the non-symmetric shape induces an additional complex behavior under torsion which needs to be assessed [12]. This explains the small number of articles on the theoretical behavior of RC flanged beams under torsion.…”

Recently, an analytical model called the generalized softened variable angle truss-model (GSVATM) aimed to predict the full behavior of reinforced concrete (RC) rectangular beams under torsion. In this article, such a model is used to compute the full torsional behavior of RC flanged beams, namely T- and L-shaped beams. The calculation procedure to include the influence of the flanges is described. A comparative analysis between the predictions from the GSVATM and some experimental results, related with RC flanged beams under torsion and found in the literature, is also presented. From this comparative analysis and for high loading levels, the GSVTM is reliable. Yet, for low loading levels, the theoretical model still needs to be refined.
