句子

1. 因为混凝土的弯曲抗拉强度为抗压强度的一小部分，素混凝土梁作为受弯构件是无效的。

Plain concrete beam are ineffective as flexural members because the tensile strength in bending is a small fraction of the compressive strength.

2.  垂直于弯曲轴线的截面在弯曲前为一平面，在弯曲后平面保持不变。

Sections perpendicular to the axis of bending that are plane before bending remain plane after bending.

3.钢筋与混凝土之间粘结可靠，以致钢筋的应变和相同位置处混凝土的应变相同。

A perfect bond exists between the reinforcement and the concrete such that the strain in the reinforcement is equal to the strain in the concrete at the same level.
