Chapter 19: Structural Steel Construction

The installation of a floor or roof deck is done by the

-general contractor -erector

A shear connection between a steel beam and a steel column is also called

a simple connection

To level a column so that it is plumb,

all of the above -steel shims are used -high-strength plastic shims are used -leveling bolts are used

A snug-tight connection between framing members is obtained by

bolting the members and tightening them with a spud wrench using full force

Which of the two-a rigid frame or a braced frame- provides greater structural stiffness, that is, greater lateral stability?

braced frame

If the floor of a steel-frame building has primary, secondary, and tertiary components, the secondary components consist of

-W-shape beams -steel joists

The central shear core in a steel-frame building

-should consists of reinforced concrete walls in both directional of the building -should consist of steel- braced frames along both directions of the building

Which of the following is not an ASTM designation for steel bolts?

A507 bolts

The difference between diagonal bracing and K-bracing between steel columns is that

all of the above -K-bracing provides less spatial interruption than diagonal bracing -K-bracing members are heavier than diagonal bracing members -K-bracing members also carry some gravity loads, while diagonal framing members do not

In a multistory steel-frame building, the columns are generally spliced.

every two floors

A multistory steel frame structure must be provided with a central shear core.

false

A rigid connection between a steel beam and a steel column can be made without connecting beam flanges to the column.

false

A steel column may or may not need a base plate at the bottom

false

A steel-frame building may consist of either a rigid frame or a braced frame. A combination of the two systems (braced- and rigid-frame systems) cannot be used in the same building.

false

If the floor of a steel-frame building has only primary and secondary components, the secondary components consist of

floor deck

Eccentric K-bracing is generally recommended for use

in seismic regions

The term racking refers to the effect produced on the structure mainly by

lateral loads

In a braced-frame steel structure, the braced bays

may be provided on the exterior facade, the interior of the building, or both

A slip-critical connection between framing members is obtained by

none of the above

Details of connections between structural steel members are prepared by the

none of the above

If the floor of a steel-frame building has primary, secondary, and tertiary components, the tertiary components consist of

none of the above

In a column splice detail, a butt plate is required when

none of the above

The erection of structural steel members is generally done by the

none of the above

The preliminary framing layout of a steel-frame building is generally presented in

plan view

The preliminary framing layout of a building is generally prepared by the

project architect

The fabrication of structural steel components is done based on

shop drawings

In connecting a steel column to concrete foundations, anchor bolts are used. These bolts are embedded into the foundation by

the general contractor

A braced frame steel structure is generally more economical than a comparable rigid frame structure

true

A shear connection between a steel beam and a steel column can be made without connecting beam flanges to the column

true

Field bolting of steel members is generally preferred over field welding

true

In connecting the upper-column shaft with a lower-column shaft in a multistory steel-frame building, we generally require

two flange plates

Camber refers to

upward deflection of a beam to counter downward deflection by a dead load
