PART II: READING COMPREHENSION (20 pts)
Part 1: Read the text and decide if the following statements are true (T) or False (F). (10pts)
Today, however, the engineer has the advantage not only of empirical information, but also of scientific data that
permit him to make careful calculations in advance. When a modern engineer plans a structure, he takes into
account the total weight of all its component materials. This is known as the dead load, which is the weight of Midterm-M.10 1
the structure itself. He must also consider the live load, the weight of all the people, cars, furniture, machines,
and so on that the structure will support when it is in use. In structures such as bridges that will handle fast
automobile traffic, he must consider the impact, the force at which the live load will be exerted on the structure.
He must also determine the safety factor, that is, an additional capability to make the structure stronger than the
combination of the three other factors.
The modern engineer must also understand the different stresses to which the materials in a structure are
subject. These include the opposite forces of compression and tension. In compression the material is pressed or
pushed together; in tension the material is pulled apart or stretched, like a rubber band. In the diagram alongside,
the top surface is concaved, or bent inward, and the material in it is in compression. The bottom surface is
convex, or bent outward, and the material in it is in tension.
21. A modern engineer calculates the total weight of all its component materials when he plans a structure
22. The dead load is the weight of the structure itself
23. One example of the “live load” is the weight of the vehicles moving on the road
24. Compression and tension are different stresses
25. When the material is in compression, the bottom surface is bent inward.
Part 2: Fill in the gaps with the words provided. (10pts) length which of cement Concrete are is regularly independent spread other reinforced
There are a lot of types of foundations in construction. The main types of 26 _______ foundations are
“independent”, “raft” and “pile”. For bridge building and 27 ______ heavy engineering structures “caisson”
foundations 28 ________ used. Independent foundations are used to support columns or piers, 29 ______ are
unevenly spaced and unequally loaded. A pad of concrete, plain or 30 _____, is placed under each column or
pier, the base of the pad extending far enough in all directions to 31_____ the load evenly over the ground. Strip
foundations are used when a row 32 _____ columns is so closely spaced that 33 _____ foundation would nearly
meet. When the columns are both near together and 34 ______ spaced, and carry nearly equal loads, raft
(sometimes called “slab”) foundations, extending the whole 35 ____ and breadth of a building, are used instead of strip foundation.
