In this study, an external reinforcement method was applied using a wire rope effective in emergency and earthquake-resistance construction methods on concrete piloti columns. To collect basic data to propose a detailed manual of this external reinforcement method using wire rope, a bearing capacity performance evaluation was conducted according to the transverse load movement of the externally reinforced RC column. A total of 7 RC column specimens were produced to comparatively examine the horizontal shear resistance of the transverse load by applying the same axial load on each specimen. Furthermore, experiments were conducted with the reinforcement method and damage state as the key variables. Based on the result of the experiment, a strength evaluation, as well as a comparison thereof to existing strength formulas, and the final fracture pattern, ductility, stiffness and deformation of the wire rope and main bars were evaluated.
