Abstract: Using high-strength reinforcements (HSRs) has several benefits in terms of financial and execution considerations. However, possible effects of HSR application on structural behavior such as ductility, energy dissipation, and damage process are not fully known for the researchers. In this study, firstly the HSR effects on the cyclic behavior, cracking process, and damage indices of special moment frames were experimentally studied under cyclic loading. Four special moment frames with HSRs (with the yield strengths of 500 and 580 MPa) were designed based on the special seismic provisions of ACI 318-19. These frames were subjected to cyclic loading and their responses were acquired. The results showed that using HSRs led to increasing the width and depth of the cracks. Then, two methods of calculating damage indices (introduced by [8].) were applied based on the experimental results. Concerning damage indices, it was observed that using HSRs generally resulted in increased damage indices of the specimens.

Key words: Special moment frames, failure process, damage indices.
