Cover Story (view full-size image): The generalized softened variable angle truss model (GSVATM) allows the global behaviour of reinforced concrete (RC) and prestressed concrete beams under pure torsion to be computed, including at the pre- and post-cracking stages. In this article, the GSVATM is extended to cover RC beams under torsion combined with external and centred axial forces. The changes in GSVATM are presented as well as the modified calculation solution procedure. Some theoretical predictions from the extended GSVATM are compared with numerical results from nonlinear finite element method, where good agreement is observed for the studied trends.
