This
paper presents a finite-element analysis of the behavior of axially-loaded,
small-scale fiber-reinforced
polymer (FRP) wrapped concrete
columns. Parameters
considered were the FRP wrap thickness, and the ply angle orientation with
respect to the lateral axis of the column. The finite element analysis results
showed considerable increase in the axial compressive strength and ductility of
the FRP-
confined concrete columns as compared to the unconfined ones. The
increase in the wrap thickness resulted in further axial strength and ductility
enhancements of the confined columns. Columns confined with the 0° angle ply
wrap exhibited the highest axial stress capacity as compared to the columns
enhanced with wraps consisted of ±15° and 0°/±15°/0° ply angles.
