The purpose of this paper is to evaluate strength and ductility capacity of strengthening using synthetic fiber rope as lateral reinforcement member of the concrete column and confirm possibility using it as alternative material of rebar. To analyze the reinforcement effect of the specimen, concrete strength, lateral reinforcement interval, lateral and reinforcement member type are set as variables to produce 14 full-size columns. This study uses the flexibility of synthetic fiber rope for lateral reinforcement of column in spiral format. To evaluate lateral reinforcement performance of synthetic fiber rope, it was compared to generally used steel tie reinforcement method and load and displacement, change rate of reinforcement member, and fracture mode were analyzed. According to such results, rebar reinforcement specimen showed load increasement ratio of 16?34%. And SM rope reinforcement specimen showed load increasement ratio of 1 - 8% while PP rope reinforcement specimen showed -6 ~ 3%. Also steel tie reinforcement specimen showed ductility fracture depending on reinforcement intervals but synthetic fiber rope reinforcement specimen mostly showed brittle fracture. As a result, lateral binding effect of concrete column through synthetic fiber rope was shown to be insufficient.
