Module 6 - Steel Framing

Who starts the building process of steel framing?

Architect (rough sketch)

Who does the structural drawings of steel framing?

Structural Engineer

What are the structural drawings used to prepare?

shop drawings (fabricator)

What do the steel framing plan depict?

shape, size, and location of structural steel (also dimensions)

What do shop drawings depict?

show the configuration and connection details of each member

What happens in the Fabrication Stage?

Ordering of materials; workers cut, drill, punch, weld, add angles, plates to steel as indicated on shop drawings

What assembles structural steel members on site in accordance to shop drawings?

The Erector

What are workers called in the Erector Stage?

Ironworkers

Steps of Structural Steel

1. Anchor Bolts & Setting Plates

2. Column Installation

3. Horizontal Framing (Beams & Girders)

4. Plumbing and Squaring

5. Secondary Horizontal Framing (Bar Joists)

6. Decking Installation

7. Detail System

3 Methods of Joining Steel Members

Rivets, Bolts, Welds

What is Riveting?

White hot fastner is inserted through holes in members to be fastened

What is this?

Riveting

Riveting is commonly used in modern construction

False

What is Bolting?

Carbon steel bolts

What is this?

Bolting

Bolting has limited uses such as fastening light framing elements or holding temporary connections

True

a bearing type connection

What do bearing type connections do?

Bolts need only be installed to “snug tight” condition.

What do slip critical type connections do?

bolts are tightened to such an extent that the friction between steel members resists movement

bearing type bolts are stressed in tension

False

bearing type bolts are stressed in shear

True

slip critical bolts are stressed in shear

False

slip critical bolts are stressed in tension

True
