Flashcards in Steel Truss Deck (16):
0

a plate, usually triangular in shape, use to connect two or more members, or to add strength to a framework

Gusset plate

1

refers to steel bar usually of 16mm or 20mm diameter rod attached at the center or end points of the span of the purlins

Sag rod

2

a structural or rolled steel in C shape used in steel construction; mosty used on steel roofing frame as purlins

Channel

3

a brace or any piece of a frame which resists truss in the direction of its own length; may be upright, diagonal or horizontal

Strut

4

a short pi, of a malleable metal such as iron, steel copper with ah head at one end, used to unite two metal plates by passing it through a hole in both plates and then hammering down the point to form a second head

Rivet

5

a connection between two members which are riveted together

Riveted joints

6

a hole to which rivet is driven

Rivet hole

7

a gastight joint obtained by uniting metal parts, such as iron and steel that require welding

Welded joints

8

5 advantages of using welded connections

1. minimal noise in the erection of the structure
2. savings on labor and materials
3. rigidity of frame
4. easy to correct new work to existing structure and also its repair
5. simplicity in design

9

the term used to indicate the depth from the original surface of the base metal to the point at which fusion ceases

Penetration

10

the failure of the weld metal and base metal to fuse at the root of the weld

Partial penetration

11

three classifications of welded joints

1. butt joint
2. tee joint
3. lap joint

12

the structural members are welded on the shop before delivering at the site

Shop weld

13

welding is done during the erection of the structural members

Field welding

14

ion connecting two overlapping plates by means of welding, hooles are made in one of the two plates then plug and slot welds are made at the entire area of the hole or slot

Plug and shot welds

15

a steel truss having an open web whose component parts are either hot-rolled structural shapes or cold-formed light-gauge steel shapes

Open-web steel joists
