急求英语高手进来翻译一下。。谢谢

麻烦翻译准确点，，。万分感谢。。呵呵

When the load is further increased, the tension strength of the concrete is soon reached and at this stage tension cracks develop. These propagate quickly upward to or close to the level of the neutral plane which in turn shifts upward with progressive cracking. The general shape and distribution of these tension cracks is shown in Fig. 2.5d. In well-designed beams the width of these cracks is so small(hairline cracks )that they are not objectionable from the viewpoint of either corrosion protection or appearance. Their presence, however, profoundly affects the behavior of the beam under load. Evidently, in a cracked section, i, e.. in . a cross section located at a crack such as a-a in Fig. 2.5d, the concrete does not transmit any tension stresses. Hence, just as in tension members, it is the steel which is called upon to resist the entire tension. At moderate loads, if the concrete stresses do not exceed approximately f’c/2, stresses and strains continue to be closely, proportional. The distribution of strains and stresses at or near cracked section is then that shown in Fig. 2.5e. When the load is still further increased, stresses and strains rise correspondingly and are no longer proportional. The ensuing nonlinear relation between stresses and strains is that given by the concrete stress strain curve. Therefore, just as in homogeneous beams the distribution of concrete stresses on the compression side of the beam is of the same shape as the stress-strain curve. Figure 2.5f shows the distribution of strains and stresses close to the ultimate load.

机译出来的东西看了真恶心~~~~！虽然分少了点，还是帮帮你吧！
译文：进一步加载时，水泥的张力强度迅速达到极限并出现张力裂缝。这些裂缝快速向上扩展或到达接近中间平面水平位置处，这也加速了向上的破裂。这些张力裂缝的一般形态和分布如图2.5d所示。在设计合理的梁上，这些裂缝的宽度是非常小的（毛细裂缝），无论对于防腐蚀保护还是外观来说都影响不大。不过它们的出现与否，还是影响压力之下的梁的性能的最直接因素。在破裂区域，这一点表现得尤为明显，比如图2.5d中破裂处的横截面a-a，水泥没有传输任何张应力，因此，在受拉杆件中，所有的张力都是钢架在承受。在中度负载情况下，如果水泥的应力没有超过大约f'c/2，那么应力和张力的比例基本持平。破裂处截面或接近截面处的应力和张力的分布见图2.5e。这时若进一步加载，压力和张力的增长就没办法再均衡了。继而压力和张力的非线性关系就成为应力应变关系曲线那样。因此，在均匀射束下，梁上面水泥受压面的应力形态应该同应力应变关系曲线一致。图2.5f显示接近负荷极限时的张力和应力分布。

当进一步增加时装载，混凝土的紧张力量很快被到达，并且拉力裂缝在这个状况下开发。这些向上迅速繁殖对或接近向上反过来转移与进步崩裂中立飞机的水平。 这些拉力裂缝的一般形状和发行在图2.5d显示。在这些镇压的宽度是那么小的设计好的射线(毛细裂缝)那他们从腐蚀保护或出现的观点不要是可厌恶的。他们的存在，然而，深刻地影响射线的行为在装载之下。 显然地，在一个破裂的部分，一个横剖面一个裂缝例如a至a位于图2.5d，混凝土不传送任何紧张重音。 因此，正在受拉杆件，它是被要求抵抗整个紧张的钢。在适度装载，如果具体重音不大约超出f’c/2，重音和张力继续严密地是，比例。张力和重音的发行在或者靠近破裂的部分的是然后在图显示的那2.5e。 当更远增加时装载，重音和张力相应地上升并且不再比例。在重音和张力之间的接着而来的非线性联系是具体应力应变曲线给的那。 所以，正在同类的射线具体重音的发行在射线的压缩边的是形状和应力应变曲线一样。图2.5f显示张力和重音的发行接近最大负载的。
