Study on the Compression Performance of CFRP Confined GFRP Short Column
In order to restrain the lateral expansion and splitting of GFRP, and accordingly heighten its axial compressive bearing capacity, a project that to confine GFRP column with surrounding CFRP sheet is suggested in the present study. Experiment on the CFRP sheet confined GFRP column shows that a combined structure of high bearing capacity is attained. Basing on the experiment research a theoretical iterative calculation approach is suggested to predict the ultimate axial compressive stress of the combined structure, and the predicted results agree well with the experimental results. Then the influences of geometrical parameters on the ultimate axial compressive stress of the combined structure are also analyzed basing on this approach.
