The first phase of the project ,which was concted at the University of Michigan, involved monotonic punching shear tests of slabs of fiber-reinforced concreted concrete 60 in.(1520mm) square and 6 in .(150mm) thick .The slabs were constructed with fibers of varying diameters, strengths, and shapes. A 1.5 percent mix of fibers by volume was created for each specimen. Of the fiber tested in the first phase , the researchers determined that a hook-shaped wire of regular strength 1.2 in.(30mm) long and 0.022in(0.55mm) in diameter, as well as a hook-shaped wire of high strength 0.015 in.(0.38mm) in diameter ,offered the highest strength and ctility . These fibers were then tested further in the second and third phases of the project.
The researchers determined that in the test specimens, the fiber-reinforced concrete needed to surround each column only to a distance equal to four times the thickness of the slab to be effective; the remainder of the slab could then be composed of standard reinforced concrete. This amount of fiber-reinforced concrete increased the amount of sway that a slab-to-column frame could experience without undergoing punching shear failure in the connections at a cost comparable to that of shear stud reinforcement, Parra-Montesinos says.
The amount of lateral movement possible in a slab-to-column connection before punching shear damage occurs is greatly affected by the gravity load present; this is typically expressed as the radio of the shear inced by the gravity loads to the punching shear capacity of the connection under the action of loads alone. According to Parra-Montesinos, without shear reinforcement, a ratio of generally associated with a roughly 1.5 percent drift capacity in the slab-to-column frame. The higher the ratio, the more likely a connection is to fail ring extreme loading. During the tests carried out in the second phase, the researchers applied a 0.5 ratio, which without slab shear reinforcement would probably lead to a punching failure at a drift of roughly 1 percent. When the connection still had not failed at a 4 percent drift, the researchers increased the ratio to 0.63. “The specimen with the high-strength fiber did not fail, and the specimen with the regular-strength fibers exhibited punching at five percent drift,” says Parra-Montesinos. “The gain in drift capacity was incredible on the unidirectional displacement tests.”

该项目的第一阶段，这是进行了在美国密西根大学，所涉及的单调冲切试验砖纤维增强混凝土的具体六零英寸（一五二○毫米）广场和6个。 （ 150毫米）厚。砖建造与纤维的不同直径，长处和形状。 1 1.5 ％的混合纤维的数量已创建为每个标本。该纤维测试在第一阶段，研究人员发现，一钩异型钢丝的经常实力1.2英寸（三零毫米）长和0.022in （ 0.55毫米） ，直径，以及作为一个钩异型钢丝高强度0.015英寸（ 0.38毫米）在直径，提供了最高的强度和韧性。这些纤维，然后测试，进一步在第二和第三阶段的项目。
研究人员发现，在测试样本，纤维混凝土所需的环绕每一栏只距离等于4倍的厚度板坯才能有效;其余的板坯，便可组成的标准钢筋混凝土。这一数额的纤维增强混凝土数额增加摆动，一个板坯到柱框架结构的经验，可无须进行冲切失败的连接在一个成本比较，认为剪切种加固，帕拉-蒙特西诺斯说。

如何分析题目
从题目部分来看，考生需要学会自己去“专业地分析题目”。平时我们做完题目只是感叹一番，那是远远不够的。建议考生从以下几个方面来通过题目研究从而提高应试能力：
第一，分析错误原因。很多人把错误归结为简单的粗心或者是文章理解不深，这是很不到位的总结。一定要注意，错误是一种规律，不同的人往往错在不同类的题目。我们需要把错误分类，只有问题更加细化明确，我们才能有的放矢的改正提高。比如，有的同学经常因为不看重表示程度的形容词或副词而导致错误，这类同学写作文时往往倾向于简单的语句，主要依靠名词和动词完成表意，他们只要在写作时有意识地运用形容词副词就能既提高写作的精确度，又能自然而然解决这类阅读题目的错误。
第二，分析出题角度。我们复习的过程事实上是不断了解考点的过程，如果我们能知道每个题目在考什么知识点，那么我们就超越了考试本身，这方面经过一定的训练就能做到。
第三，联系多年题目。做过很多题目后，要对重点题目留下深刻印象，并且把不同年份的题目联系起来，这能让我们对考试走向、出题规律有比较精准的把握。

另外，当你单词不会的时候，一定要勤于翻翻字典或词典，一定要呀！因为，当你不懂时，你的注意力是最为集中，这个时候记忆，效果最佳！

Once upon a time there lived an old man. He had three sons. One day, he called them together and said, "Sons, I will die soon. To my oldest son I give half my camels, to my second, one-third(三分之一), and to my youngest, one-ninth (九分之一)." Soon after that he died.
Now, the old man had seventeen camels, and the three brothers didn't know how to do as their father said. They thought a long time about the problem, and it seemed that they must either kill some of the camels and cut them into pieces, or disobey their father.

I have only one camel, but take it-it is yours."
The three sons thanked the old man and took his camel. Now they found it was easy to do as their father wished, The oldest took half- that was nine camels; the second took one-third, that was six; and the youngest took one-ninth, that was two.

We know mosquitoes very well. Mosquitoes fly everywhere. They can be found almost all over the world, and there are more than 2,500 kinds of them.
No one likes the mosquito. But the mosquito may decide if she loves you. She? Yes, she. The male mosquito doesn’t bite! Only the female mosquito bites because she needs blood to lay eggs. She is always looking for things or people she wants to bite. If she likes what she finds, she bites. But if she doesn’t like your blood, she will turn to someone else for more delicious blood. Next time a mosquito bites you, just remember you are chosen. You’re different from the others!
If the mosquito likes you, she lands on your body without letting you know. She bites you so quickly and quietly that you may not feel anything different. After she bites, you will have an itch(痒) on your body because she puts something from her mouth together with your blood. When the itch begins, she has flown away.
And then what happens? Well, after her delicious dinner, the mosquito feels tired. She wants to find a place to have a good rest. There, in a tree or on a wall, she begins to lay eggs, hundreds of eggs.

Do you know why different animals or pests(昆虫) have their special colours? Colours in them seem to be used mainly to protect themselves.
Some birds like eating locusts(蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colours together with the change of the colours of crops(庄稼). When crops are green, locusts look green. But as the harvest (收获)time comes, locusts change to the same brown colour as crops have. Some other pests with different colours from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you’ll find the main use of colouring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters. This is because they have the colours much like the trees.
Have you ever found an even more strange act? A kind of fish in the sea can send out a kind of very black liquid(液体) when it faces danger. While the liquid spreads over(散开), its enemies(敌人) cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.

A. are small animals
B. are easily found by birds
C. are dangerous to their enemies

( )57.How can pests with different colours from plants keep out of danger?
A. They run away quickly.
B. They have the colours much like their enemies.
C. They hide themselves by day and appear at night.
D. They have to move quietly.
( )58.Bears and lions can keep safe because________.
A. they have the colours much like the trees
B. they move quietly
C. they like brown and grey colours
