COSC 354 EXAM 2 QUESTIONS & ANSWERS
What material does the ironworker typically use during steel erection to temporarily hold
the steel in-place until bolts can be installed? - Answer -Drift Pins
In a two-way floor/roof system, the heavy reinforcement that is designed to carry the
higher bending forces encountered in the zones of the slab that cross the columns is
called what? In class, it was described as a "Grade beam within the depth of the slab". -
Answer -Column Strip
In a two-way flat slab, the mushroom capital or the drop panels are built to resist what in
the structure? - Answer -High Shear Forces at the top of the column
How does weathering steel differ from conventional carbon steel in construction? -
Answer -Its unique composition allows it to develop a protective layer of rust, which
eliminates the need for painting and provides enhanced corrosion resistance over time
As discussed in class, at what temperature does steel rapidly lose its yield strength? -
Answer -500-600 degrees
When making column splices on multi-story buildings, where is the splice usually made?
- Answer -Wait Height Above the Floor
When discussing the ways to stabilize a building horizontally from lateral forces, i.e
wind, the method that uses solid walls of concrete, or concrete masonry is called: -
Answer -Shear Walls
When a beam connection needs to be made to a girder, and the top side of the steel
members need to be the same height, what is it called when the flange of the beam is
cut? - Answer -Coped Beam
What structural steel member did the Wide Flange Beam replace because it is much
more structural efficient? Also known as the I-beam. - Answer -American Standard
Beam
These type of bolts are typically used as a temporary means of steel installation. These
are also used in light framing scenarios: - Answer -Carbon Steel Bolts
Before steel goes through the rolling mills, the steel is fabricated into standard shapes
that are typically thick approximations of their final shape. What is the steel called at this
step? - Answer -Beam Blanks
What is true about using Insulated Concrete Forms (ICFs) in construction projects? -
Answer -Include enhanced energy efficiency, superior sound insulation, increased
strength and durability, and accelerated construction timelines
