| Abstract: | In this paper,the formula of flexural stiffness of unbounded prestressed concrete beams are developed by the method of material mechanics.It is shown that the contribution to the flexural stiffness of the unbounded tendons is smaller than that of the bounded tendons.The layout of unbounded tendons and the loading conditions are also simply analyzed. |

| Keywords: | prestressed concrete unbounded flexural |
