The double-spiral is a device of two interconnected spirals including a circular spiral at the center and a “ star-shaped spiral”surrounding the perimeter of the rectangular column. The innovative application of the star-shaped spiral to rectangular SRC columns is to take its superiority in concrete confinement at the four corners of the rectangular column as well as its efficiency in automatic production for the precast construction industry. The major parameters of this study included the cost effectiveness of the double-spiral, the axial strength and the ductility of the spirally confined SRC columns. As compared to the reinforced concrete column tied with traditional rectangular hoops, the test results revealed that, with significant cost savings of the confinement reinforcement, the SRC columns confined with the double-spiral demonstrated excellent capability in both strength and ductility.
