The study presented herein aims to comprehensively investigate the structural performance of the cable-cylinder bracing system as a promising alternative to the conventional X-cable bracing system. To this end, the theoretical background of this system and its governing equilibrium relationships are presented. Subsequently, the effect of cylinder dimension and the level of prestressing force on the behavior of this system are discussed. Then, the nonlinear static and dynamic responses of this bracing system are compared with those of the conventional cable bracing system. Using the incremental dynamic analysis results, the response modification factor of this system is estimated. Finally, a sensitivity analysis is carried out on this system, and an equation is proposed for the R factor (response modification factor) of the proposed cable-cylinder bracing system.
