ABSTRACT
Abstract The PVC‐CFRP confined steel reinforced concrete (PCSRC) is a composite structure formed by embedding inside PVC‐FRP pipes and pouring concrete. It boasts advantages such as high bearing capacity, corrosion resistance, the ability to withstand substantial plastic deformation. pipe created intermittently winding CFRP strips on surface of PVC pipe. To investigate mechanical properties PCSRC in short columns, 10 specimens under axial compression, varying different parameters including section diameter, content, yield strength H‐shaped steel, strip spacing, are designed. test results revealed that primary damage modes observed tube bursting rupturing. ultimate capacity increased with larger diameters, higher strength, greater narrower spacing. Moreover, increases, rate degradation compressive rigidity also accelerates, while other have relatively minor influences. Based these experimental findings, theoretical formula predict compression developed, it aligns well results.
