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
