1
a frame structure is made up of struts poles bars and b e a m s
2
the resist the force of bending
3
a long piece of timber or metal or concrete supported at each end by columns
4
tie beam, rafter, king post, strut, strut, rafter
5
tie beam, rafter, king post, strut, strut, rafter
6
principal rafter, Queen post, Queen post, rafter, rafter, t i e b e am
7
stationery forces they do not move
8
moving forces wind people
9
shear force tearing, torsion Force twisting, tension Force pulling, compression Force pushing, bending Force applied at an angle
10
changing in shape
11
to put things together
12
constructed or put into position and set upright
13
long round and hollow like a tube
14
Steel concrete wood
15
the cables of an electrical pylon have to be very high, destruction is designs that you cannot be climbed, this structure must be in the form of the frame so that wind can easily pass through without blowing it over
16
Buzzard form the shape of an X which supports structure
17
the combination of struts and beams to form triangles
18
the ability of a material to be unaffected by corrosion caused by acids air and water
19
bars that are joined at angles two structures
20
unable to bend or B forced out of shape
21
Close or create a bridge
22
having many different and connected parts
23
a girder is a supporting Beam in a structure
24
resist s h e a r i n g force and bending
25
designed to bear loads in building construction
26
the beam Bridge rest on simple columns, a beam may be built away from the final position and lifted into place
27
the beam Bridge experiences large amounts of forces therefore it has to be big in size
28
the columns hold the main cable up the Anchors pull the cable outwards and downwards the hangers can connect the deck to the main cable the deck carries the traffic
29
to hold the ends of the main cables
30
to hold the deck up
31
connect the deck to the main cable
32
the deck has to be as light as possible but stiff enough to prevent a dip as each vehicle passes
33
suspension bridges can span very long gaps, if one of the hangers fails or breaks it can be replaced without disruption to traffic, suspension bridges do not have to be built along straight channels, suspension produce can be built with double decks
34
suspension bridges are very expensive, they take a very long time to build, the concrete tiles have to be built in Shallow bedrock, the incomplete decks can be affected by strong winds
35
the two halves May be cantilevered out from each side, there is no need for anchors, they give me cheaper than suspension bridges
36
in the longest sizes the c a n t i l e v e r e d r can be affected by strong winds during construction, the cables require careful treatment to protect them from corrosion
