title = "Numerical Simulation of RC Beams Strengthened by Post-tensioning",
abstract = "In the present paper, a numerical simulation performed in the structural analysis framework OpenSeesPy (Python interpreter for OpenSees) of post-tensioned strengthening solutions for RC beams in frame systems, proposed by Gi{\~a}o and Muhaj, is presented. Two reference specimens (VR2 and CB1) and three strengthened specimens were evaluated—one specimen strengthened with non-adherent exterior post-tensioning strands (VPE) and the other two specimens strengthened with interior post-tensioning strands with anchorages by bonding (CB2 and CB3). The two strengthened solutions under analysis aimed to improve the hysteretic behaviour of the beams and, if the techniques are applied to frames, avoid the development of unidirectional plastic hinges. The models were loaded simultaneously with cyclic horizontal displacements and significant gravity loads. The numeric results are analysed and validated by comparison with the experimental ones. The strengthened solutions displayed greater energy dissipation and minor residual deformations than the reference specimens, showing to be adequate seismic strengthening techniques.",
