预应力混凝土
别来机译，谢谢！
Deflection calculations for uncracked prestressed sections tend to be more accurate than those for cracked sections since the assumptions of elastic behavior are more applicable. The use of the moment of inertia of the gross section rather than the transformed section does not appreciably affect the accuracy sought in the calculations.

对预应力混凝土未开裂截面的挠度计算，比开裂截面的挠度计算更准确，因为弹性变形的假设更适合前者。在挠度曲线的计算过程中，用原截面的惯性矩而不是用变形后截面的惯性矩，对结果的精确性影响不大。
无裂缝的预应力部分的偏斜计算应尽量比裂缝部分的更精确，因其理论弹性更合适。使用毛截面的惯性力矩比用换算截面更有利于计算的精确性。
。。。。。。。
有没有真正专业高手来指点下下哦？
我来吧~~~预应力混凝土应该是大三了吧~呵呵
由于更加适用弹性性能的假定，无缝预应力梁的挠度计算往往比有缝的更精确。使用全截面的惯性矩而不是用换算截面并没有明显影响计算的精确度。
