Which of the following is a characteristic of Galvanized Iron (G.I.)?
Contains between 0.12% - 2.0% carbon.
Coated in a layer of zinc to resist corrosion.
Cheaper and more common in steel construction.
Easily rusts and requires frequent maintenance.
What is the primary purpose of reinforcement bars (rebar) in concrete structures?
To increase the weight of the concrete.
To act as a compression device in reinforced concrete.
To aid concrete in carrying tensile loads and strengthen it under tension.
To replace concrete in areas requiring higher strength.
Which of the following is categorized as a tubular section in typical steel components?
UB/WF/SF
SHS, RHS, CHS
C & Z channels
Steel bars, plates, and sheets
What are light-gauge steel sections typically used for?
Supporting heavy structural loads
Secondary structural members and framing
Decorative elements in buildings
Flooring material in timber buildings
How do arch frames primarily transfer forces to the ground?
Through tension within the structure
By bending forces along the arch
By distributing forces evenly across cables
Through compression within the structure
What is a common characteristic of both arch and tension frames?
Both use cables for tension
Both rely entirely on compression forces
Both can span large areas (long spans)
Both require tubular members for buckling resistance
Which type of support frame is designed to prevent any movement or rotation?
Fixed Support Frames
Rolled Support Frames
Arch Frames
Tension Frames
What is the purpose of rolled support frames in steel structures?
To ensure stability by preventing movement
To support thermal expansion and contraction
To allow horizontal movement
To provide additional tension to the structure
What is the purpose of mesh reinforcement in composite slabs?
To increase the weight of the structure
To reduce cracking and spread localized loads
To eliminate the need for shear connectors
To replace concrete in the slab
What is the function of the metal deck in the composite slab system?
To act as permanent flooring
To act as a base before pouring concrete above it
To provide additional thermal insulation
To span long distances without beams
What is the primary purpose of web openings in composite beams?
To reduce the weight of the beam
To improve aesthetic appearance
For the passage of services within the beam depth
For ventilation
What is the primary purpose of the Slimdek floor system?
To support shallow composite decking with minimal reinforcement
To eliminate the need for reinforcement in the slab
To reduce overall building height and cladding
To increase the weight of the floor system
