Abstract
. Carbon fiber reinforced composite materials (CFRP) have a wide range of applications in the field of engineering reinforcement. This article establishes a constitutive model, constructs a calculation model for ultimate bearing capacity, and derives formulas for the axial compressive strength and ultimate compressive bearing capacity of confined concrete. By comparing the calculated bearing capacity with the design value, the feasibility of the formula is verified, indicating that the strip CFRP circular steel tube lithium slag concrete column is in a safe state, indicating that the prediction model has good applicability.
