Study on limit axial-load ratio of PVC-FRP confined reinforced concrete column
The mechanical behavior of PVC-FRP confined reinforced concrete column are analyzed according to the stress-strain relationship of confined concrete.Based on the equilibrium condition of large and small eccentric limit compression,the basic assumptions for limit axial-load ratio of PVC-FRP confined reinforced concrete column are proposed,and then a calculating method of limit axial-load ratio is derived.It is shown that the limit axial-load ratio of PVC-FRP confined reinforced concrete column decreases with the increment of the hoop spacing of CFRP strips,the limit axial-load ratio of PVC-FRP confined reinforced concrete column are greatly improved compared with that of reinforced concrete column.
