如果预应力筋达到EN 10138中的最大荷载下的延伸率规定值，则可以假定其在延伸时有足够的塑性。

Adequate ductility in elongation may be assumed if the prestressing tendons obtain the specified value of the elongation at maximum load given in en 10138.

计算结果表明：该桥在设计荷载下的最大挠度值及应力值均小于规范规定值，结构处于安全的范围内。

The result show that: under the design load the maximum deflection and stress is less than code values, the bridge is safety.
