| Abstract: | This paper simply introduces the secondary moment's influence on the ultimate capacity of the prestressed statically indeterminate structure,briefly analyses the differences and similarities of the influence on the design standards in foreign countries.Based on the load increment method, it analyses a two span prestressed continuous conerete beam's all loading\|falisure phases here,and calculates the affects of the plastic redistribution and secondary moment. |

| Keywords: | prestressed concrete secondary moment the ultimate capacity continuous beam |
