Architecturally exposed structural steel (AESS) does NOT require the following:
- Cleaner finishes
- Tighter gaps at connections
- Better quality surface preparation
- Connections must be welded (not bolted)
If your project has feature elements greater than 20 ft from view, grinding of welds is not required, and bolted connections can be visible and nonuniform, which of the following AESS categories could your project fall in?
- AESS 1
- AESS 2
- AESS 3
- AESS 4
Which of the following statements is true?
- HSS can be easier to work with for AESS due to their resistance to twisting during handling, delivery, and erection.
- Increasing wall thickness of HSS makes it easier to bend
- Round tubes generally experience less deformation during bending than rectangular tubes.
- All of the above
Which AESS category below calls for the HSS weld seam not to be apparent, which may require grinding of the weld seam?
- AESS 1
- AESS 2
- AESS 3
- AESS 4
Which of the following allows for ‘hidden’ HSS connections
- Casted connections
- Interior splice plates
- Cover plated connections
- All of the above
For AESS Categories 2, 3, and 4, what are the permissible HSS tolerances as compared to the standard non-AESS tolerances?
- One-fourth of standard tolerances
- One-half of standard tolerances
- Same as standard tolerances
- Double the standard tolerances
What is the permissible corner radius tolerance for HSS in AESS Categories 2, 3, and 4?
- 1.5 times wall thickness
- 2 times wall thickness
- 3 times wall thickness
- None of the above
The temperature of the zinc bath for galvanizing is roughly:
- 550°F
- 680°F
- 770°F
- 830°F
Which of the following is recommended for galvanizing HSS?
- A duplex system of painting after galvanizing
- Specify vent and drain hole locations on contract documents
- Where possible, minimize the size of pieces to be dipped
- All of the above
Which of the following is a correct location for galvanizing vent holes in HSS?
- Anywhere
- At the top and bottom of the HSS member
- Far from the end of the HSS member
- Vent holes are not required
- Yes, I would like to receive new information about HSS, its specifications, uses and capabilities
