Abstract: In the process of construction of concrete structure,the principle of replacing reinforcement with equal intensity is often used to replace the stressed reinforcements.According to the national standardCode for Design of Concrete Structures(GB 50010-2002),it was analyzed the effect of reinforcements diameter,shape,type and intensity on the stiffness,crack,anchorage,transferring of prestressing force and failure form of a structural member.It indicated that attentiona should be paid to replacing reinforcement in construction,and it should be conducted the document of design change according to demands on the national standardCode for Acceptance of Constructional Quality of Concrete Structures(GB 50204-2002).
