【Abstract】 The paper analysed the behaviors of the GFRP-confined Concrete Column the axial compression by experiments and showed that there’s different mechanical properties between GFRP-concrete and Steel-concrete. According to the test results the study set up a model for the Stress-strain relationship of the FRP-confined Concrete Column under the axial compression and developed the guantitative analysis of the cohole Stress-strain curve under the axial compression . Furthermore the influence of the Poisson’s ratio and load -sustain stress of the GFRP tubes on the strength of the combined Structure was proposed.更多还原
