COSC 354 exam 2 Questions and Answers Fully Solved Latest Version 2025-2026
What material does the ironworker typically use during steel erection to temporarily hold the
steel in-place until bolts can be installed? - Answers 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". - Answers Column Strip
In a two-way flat slab, the mushroom capital or the drop panels are built to resist what in the
structure? - Answers High Shear Forces at the top of the column
How does weathering steel differ from conventional carbon steel in construction? - Answers 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
When performing a weld, air needs to be kept out of the weld to keep from rapid oxidation. This
is mostly commonly resolved by: - Answers Gaseous Shield
Similar to a one-way joist system, this type of one-way floor system allows for longer span joists
because of a thickened slab section: - Answers Skip-Joist System
What distinguishes ferrous metals based on their carbon content? - Answers Their carbon
content predominantly determines their mechanical properties, such as strength and hardness

When making column splices on multi-story buildings, where is the splice usually made? -
Answers 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: - Answers Shear Walls
