Research on Stress-Strain Relationship Model of Concrete Prism Confined by GFRP
Study the properties of GFRP confining concrete column through eight groups columns subjected to axial loading, and receive the stress-strain curves; various design parameters, such as amounts of GFRP sheets, width of straps and spacing of straps, have been considered. The results are: The axial compressive strength and ductility of concrete prism wrapped by GFRP sheets or GFRP straps have all increased to a certain degree, the process of destruction of concrete prism wrapped by GFRP become slower than common concrete prism. Based on the test results, deducing and validating the stress-strain relationship model of GFRP confining concrete prism.
