Experimental research on axial compression performance of square section concrete column confined by FRP

To Study the axial compression performance of FRP confining concrete square section column through sixteen groups columns subjected to axial loading; various design parameters, such as types of FRP, amounts of FRP sheets, width of straps and spacing of straps, have been considered. The results are: The axial compressive strength and ductility performance of concrete square section wrapped by FRP sheets or FRP straps have all increased to a certain degree.
