| Abstract: | Based on the related research on fiber reinforced polymer （FRP） confined concrete column, authors presented the state-of-the-art review of FRP confined concrete column and gave a comment on some related factors from the following aspects： the relations of stress and strain, the axial compression, mechanics behavior of eccentric compression, seismic performance as well as finite element numerical simulations of FRP reinforced columns. Several key parameters impacting on FRP strengthening effect were discussed, such as lateral confinement strength, stiffness, the type of FRP, section shape of column, unconfined concrete strength, corner radius, length-width ratio of section, etc. The results provide reference to further research of FRP retrofitting concrete columns. |
