25
Can you use a DTI as a tension callibrator for preinstallation verification on fastener assemblies that use DTI installation method?
Yes, but the verification DTI must be placed on the end opposite of the production DTI
26
During DTI pretensioning, what does the installer do?
Checks the job inspection gap
27
What should happen if the splined end of the TC bolt is devered during snug tightening?
Remove and replace the fastener assembly
28
Why are bolts in the field installed to a pretension that is less than the preinstallation verification?
The higher pretension during pre-installation provides confidence that the field pretension can be met
29
Where does the washer go for DTI pretensioning where the bolt head is turned and the DTI is under the bolt head?
Between the bolt head and the DTI
30
If the job inspection gap for DTI pretensioing is 0.015" , then:
The DTI must be compressed to the gap less than 0.015
31
Given: the torque value determined from the most recent pre-installation verification for calibrated wrench pretensioning is 650 foot-pounds. How much torque should be applied to the bolts in the field?
650 foot-pounds
32
Is a washer required for calibrated wrench pretensioning?
Yes, underneath the turned element
33
Matchmarking refers to:
Marking a straight line over the nut and bolt to match them together
34
For turn-of-nut pretensioning, if the bolt is 4" long and 1-1/8" in diameter and one face of the bolted ply is sloped at 1:20, then:
Do not use beveled washer
35
For DTI pretensioning, if the bolt does not have a washer or DTI, then:
The nut is turned
36
When inspecting a joint that uses calibrated wrench pretensioning, would a pretension greater than the required amount be a cause for rejection?
No, the bolt is still considered adequate
37
Routine observation means:
Periodic monitoring of the work in progress
38
Which pretensioning method probably requires more frequent routine observations?
Calibrated wrench because you can't determine appropriate torque after the bolt is installed
39
If turn of nut pretensioning required a 2/3 nut rotation, how would match marking be used for inspection?
By marking the nut and bolt together after snug tightening, then checking the distance between the 2 marks after pretensioning
40
When inspecting a slip-critical joint, it is inspected just like a pretensioned joint, except:
Slip critical faying surfaces have additional requirements
41
The inspector must document acceptance or rejection of how many bolted connections in a structure?
Each one
42
Special inspection tasks and frequencies are found in which publication
AISC 360
43
Who provides the quality control program?
The fabricator
44
AISC 341 is the designation for:
Seismic Provisions for Structural Steel Buildings
45
Who can perform steelwork without any QA inspection besides non-destructive testing?
The fabricator
46
Observing that a fastener assembly of suitable condition is placed in all bolt holes of a joint would be considered:
An inspection task during bolting
47
Arbitration torque refers to
The torque value used to test bolts in question
48
When a joint with a 1-1/4" ASTM A490 bolts undergoes an arbitration procedure, the representative bolt pretension must reach:
102 kips
49
During an arbitration procedure, a representative bolt sample is pretensioned to approximately
The minimum value required during pre-installation verification divided by 1.05
50
If the representative bolt samples were correctly pretensioned to 80 kips during arbitration procedure, what is the arbitration torque?
The amount of torque required to turn the bolt head or nut an additional 5 degrees
51
The amount of pretension required for a representative bolt during arbitration is equal to:
70% of the bolt's specified minimum tensile strength
52
In an arbitration procedure, 3 is the:
Number of bolts averaged to determine the arbitration torque
53
The wrench used in an arbitration procedure must:
Be able to indicate torque
54
If a bolt or but head of a join in question is turned during arbitration testing, then:
The remaining bolts in the joint must be tested.
55
Shop drawings shall be prepared:
In advance of fabrication
56
Unidentified steel is permitted to be used only for members when ____ and ____
Their failure will not reduce the strength of the structure, Approved by the engineer
57
At what point should column base plates be grouted?
After the structural steel frame is plumbed
58
When should column anchor rods be shipped to the project site?
When needed for anchorage
59
For existing structures, which of the following is not within the erector's scope of work?
Demolition
60
The identification capability for steel shall include:
