GB/T 45467-2025
ActiveFiber reinforced polymer composite tubes for confining concrete
约束混凝土用纤维增强复合材料管
Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and packaging for fiber reinforced polymer (FRP) composite tubes used to confine concrete. It is applied in civil engineering and infrastructure projects, such as bridge piers, columns, and seismic retrofitting, where the tubes provide external confinement to enhance the compressive strength and ductility of concrete under axial loads. The standard ensures consistent quality and performance for these composite tubes in structural reinforcement and new construction applications.
