Chapter 6 Structures

• 1. Abutment the supports where a bridge arch
  meets the ground they resist the outward thrust
  (push) and keeps the bridge up.

2

• 2. Arch Bridge a type of bridge in which the
  compressive stress created by the load is spread
  over the arch as a whole.

3

• 3. Cantilever Bridge a type of bridge in which
  a beam is capable of supporting a load at one end
  when the opposite end is anchored or fixed.

4

• 4. Compression a squeezing force

5

• 5. Dynamic Load A load on a structure that is
  always changing.

6

• 6. Load the weight, mass, or force placed on a
  structure in an electrical circuit, any
  current-using device.

7

• 7. Pier a structure used to support the center
  of a bridge.

8

• 8. Reinforced Concrete concrete in which steel
  rods have been embedded to increase the
  concretes resistance to tension.

9

• 9. Shear A multidirectional sliding and
  separating force.

10

• 10. Static Load a load that is unchanging or
  changes slowly.

11

• 11. Stay Cables that support a bridge deck from
  above.

12

• 12. Structure Something that encloses and
  defines a space also, an assembly of separate
  parts that is capable of supporting a load.

13

• 13. Strut A rigid structural member that is in
  compression.

14

• 14. Suspension Bridge a bridge in which the
  deck is suspended (hung) from hangers attached to
  a continuous cable, which passes over towers and
  is anchored to the ground at each end.

15

• 15. Tension a pulling force

16

• 16. Tie A rigid structural member that is in
  tension

17

• 17. Truss A structural element made up of a
  series of triangular frames.
