| Abstract: | Based on the design code of concrete structure(GBJ10-89), the paper gives the nominal tensile stressmethod of controlling crack width in prestressed concrete structure of punchy bars. It gives conditionfor accounting area of common bars and area of prestressing bars by equations of crack controlling andcapacity carrying. |
