  • Torsion can be a significant action in many structural members that are part of civil engineering infrastructure. Gravity loads can induce torsional stresses in curved bridges and spandrel beams. Seismic loads can induce cyclic torsion combined with other actions in the beams and columns of bridges with outriggers. Reliable models are needed to predict the effect of torsional stresses on a reinforced concrete (RC) member's hysteretic load-deformation response, and also on the monotonic behavior at service and ultimate load levels. Little previous research has focused on the hysteretic behavior of RC members under cyclic torsion and torsion combined with other actions. This research study was intended to improve the understanding of the behavior of such members and provide analytical...
