Deck 17: Steel Frame Construction

Question 1

____ drawings contain the necessary information for the fabrication of each member.

A) Shop
B) Design
C) Erection
D) Plan

Answer 1

A

Question 2

What are precast hollow-core decking units and when are they used?

Answer 2

Precast hollow-core decking units, used for long spans, are placed on the steel framing with a crane. For better bonding with topping materials, their top surface is often left rough. The topping helps tie precast units together and increases a roof's or floor's structural integrity. Reinforcing can be cast in the topping.

Question 3

What are open-web joists?

Answer 3

Open-web joists are a type of truss. They are lightweight structur al members made from steel angles and bars. They, like other trusses, are end bearing and can span long distances in floor and roof constructions.  Steel open-web joists typically require cross bracing to prevent twisting.

Question 4

____ use steel columns and openweb joists and girders to form a roof.

A) Rigid frame buildings
B) Truss-type buildings
C) Post-and-beam framed buildings
D) Sloped roof buildings

Question 5

____ are formed from flat cold-rolled pieces of carbon steel.

A) Tensile structures
B) Cable nets
C) Light-gauge structural steel shapes
D) Tensioned fabrics

Question 6

Describe cellular steel-floor raceway systems and its advantages.

Question 7

____ troweled over a metal lath is a lightweight fire protection material.

A) Fire-resistant sheets
B) Lightweight plaster
C) Mineral fiber
D) Gypsum blocks

Question 8

____ are installed in holes that are drilled or punched in framing members.

A) Bolts
B) Rivets
C) Screws
D) Nuts

Question 9

A ____ is a coplanar (forces operating in the same plane) assembly of structural members joined at their ends.

A) truss
B) precast unit
C) channel
D) plank

Question 10

____stress is produced when vertical loads are applied to a member, creating a deformation in which parallel planes slide relative to each other.

A) Tensile
B) Rotational
C) Shear
D) Compressive

Question 11

Describe the common types of pre-engineered metal building systems.

Question 12

What are friction connections?

Question 13

____ frames are a three-dimensional truss system that can achieve very long spans .

A) Open-web
B) Space
C) Pratt
D) Howe

Question 14

Explain how a guy derrick is used in multistory construction.

Question 15

The Specification for Structural Steel Buildings (AISC 2005) defines two types of connections: simple connections and ______ connections.

A) seated
B) framed
C) rigid
D) moment

Question 16

____ decking uses a concrete topping poured onto metal decking to provide a strong and stiff structural floor system.

A) Cellular steel-floor raceway
B) Concrete
C) Acoustic steel
D) Composite metal

Question 17

What is galling and how can it be prevented?

Question 18

Briefly describe the metal connections that may be used to make up a steel frame.

Question 19

What are flame shields?

Question 20

What types of drawings are required for steel frame construction?
