000021878 520__ $$2eng$$aThe cyclic response of existing Reinforced Concrete (RC) frames upgraded using diagonal X-type steel elements as tension-ties is experimentally investigated. Test results of two single-story single-span RC frames subjected to cyclic imposed lateral deformations are presented. The dimensional and the reinforcement configurations of the examined frames are the same and represent typical RC frame structures that have been designed and constructed using old Code provisions without consideration of seismic design criteria. The columns of the tested frames have shear-critical character due to the inadequate amount of stirrups provided and their low height-to-depth ratio (short columns). The experimental program includes a bare frame and a strengthened one using a pair of two steel crossed tension-ties (X-type bracing). Emphasis is given to the unilateral behavior of the steel bracing elements that undertake only tension stresses. In a companion paper, the herein experimental results are simulated and used as a comparative basis for the calibration of a numerical approach concerning a typical example problem.
