The efficiency of combining fine aggregate's (sand) partial replacements with waste crumb rubber (CR) and steel fiber (SF) has been investigated in this paper. The study aims to enhance the RC frame's deformability, as well as its structural ductility to achieve progressive collapse resistance. To this end, a total of four RC frames' behavior at one-third scale under a situation of a middle-column removal was experimentally tested. Two frames were made of 0% CR and SF. Another two frames were made by incorporating CR at 20% by volume for the sand replacement and 0.5% SF fraction volume. The findings of the study reported an enhanced structural ductility, which was stimulated by incorporating CR and SF in normal concrete. The tested steel fiber-reinforced rubberized concrete frames, however, showed further deflection by 29.5% compared with the conventional frames.
