1.Deck structures predominate:they have a clean appearance,provide the motorist with a better view of the surrounding area,and are easier to widen if future traffic requires it.
2.The cables provided aboved the deck and connected to the towers would permit elimination of intermediate piers facilitating a larger width for purposes of navigation.
3.In recint decades,there has been a growing concern among many prominent engineers that not only is the term "factor of safety"improper and unrealistic,but worse still a structural design philosophy based on this concept leads in most cases to an unduly conservative and therefore uneconomical design,and in some cases to an unduly conservative design with too high a probability of failure.
4.In addition to tention and compression,another force is at work namely shear,namely shear, which we defined as the tendency lf a material to fracture along the lines of stress.
5.The force prevents the cracks from developing by eliminating or considerably reducing the tensile stresses at the critical midspan and suport sections at service load,thereby raising the bending,shear,and torsional capacities of the sections.

接楼上hy2004的翻
2.The cables provided aboved the deck and connected to the towers would permit elimination of intermediate piers facilitating a larger width for purposes of navigation
2.面板上提供的与塔状物相连的线缆能够容许消除因行驶目的加宽而设的中间支柱.
太专业了,不太理解其中的具体部件.呵呵!
3.在最近几十年里,许多顶尖的工程师越来越多的关心不仅仅是"安全因素"的提法不正确和不现实,而是由于上面观点的存在而导致的设计指导思想在许多方面已产生了不必要的保守倾向和不经济的设计以及在某些方面由于太过保守的设计而导致失败的概率高的惊人.
4.除了紧力和压缩力以外,在其工作中还有另一种力称为剪力,那就是我们在一种材料沿应力线发生断裂时所定义的倾向趋势.
5.这种力通过消除或相对减少在关键性的中跨和承载时的支撑区的张力而阻止裂纹的进一步扩大.于是提高了这部分的弯曲性,剪力性和扭距范围,

.Deck structures predominate:they have a clean appearance,provide the motorist with a better view of the surrounding area,and are easier to widen if future traffic requires it.
面板结构至关重要:它们外观整洁,为摩托驾驶者提供了一个周围地区的更好的视角,并如果未来交通需要的话,可以比较容易的加宽

是否未来交通需要它, 1.deck structure 掌握:他们有干净的外表,提供周围的区域比较好的视野给乘汽车者,而且是比较容易弄宽的。
2.The 电缆提供上方甲板而且连接给塔会允许中间的码头为航行的目的帮助比较大的宽度除去。
3.In recint 十年 ,在许多显着的工程师之中已经有成长的关心以不但是术语 " 工作率" 不合适的和不切实际的 , 而且更坏的事使被基於这项观念引入的最大多数的情形到的一种结构的设计哲学安静一不适当地保守因此 uneconomical 设计,和在某些情况对一不适当地保守的设计和太高度地失败的可能性。
对 tention 和压缩的 4.In 附加,另外的一个力量是在工作中即修剪,即修剪,我们定义如趋向 lf 材料沿着压迫力的线破碎哪一。
5.The 力量阻止 cracks 藉由除去发展或非常地在紧要关头的 midspan 减少张应力和在服务减少 suport 区段装载,藉此升起那弯曲,修剪 , 和区段的扭力能力。
