Steel Structures MCQs : This section focuses on the "Basics" of Steel Structures. These Multiple Choice Questions (MCQs) should be practiced to improve the Steel Structures skills required for various interviews (campus interview, walk-in interview, company interview), placement, entrance exam and other competitive examinations.
______________ is an area of structural engineering used to design steel structures.
A. structural analysis
B. structural loading
C. structural steel design
D. structural load
Explanation: structural steel design, is an area of structural engineering used to design steel structures.
Steel structures include?
D. All of the above
Explanation: These structures include schools, houses, bridges, commercial centers, tall buildings, warehouses, aircraft, ships and stadiums. The design and use of steel frames are commonly employed in the design of steel structures. More advanced structures include steel plates and shells.
How many common methods of steel design?
Explanation: There are currently two common methods of steel design: The first method is the Allowable Strength Design (ASD) method. The second is the Load and Resistance Factor Design (LRFD) method. Both use a strength, or ultimate level design approach.
A steel structure is composed of structural members that are made of steel.
C. Can be true or false
D. Can not say
Explanation: True, A steel structure is composed of structural members that are made of steel, usually with standard cross-sectional profiles and standards of chemical composition and mechanical properties.
Steel is mainly an alloy of
A. Sulphur and Zinc
B. Iron and Carbon
C. Zinc and tin
D. Phosphorous and Tin
Explanation: Steel is alloy of iron and carbon. Apart from carbon, a small percent of manganese, sulphur, phosphorous, chrome, nickel, and copper are added to give special properties to steel.
Which of the following is a disadvantage of Steel?
A. High strength per unit mass
B. High durability
C. Fire and corrosion resistance
Explanation: Steel has high strength per unit mass, highly durable, and is reusable. But steel is poor in fire and corrosion resistance, it needs to be protected.
Poisson’s ratio of steel is ________
Explanation: Poissons ratio = transverse strain/axial strain. As per IS 800-2007, Poisson’s ratio of steel is 0.3 in elastic range and it is 0.5 in plastic range.
What happens when Manganese is added to steel?
A. decreases strength and hardness of steel
B. improves corrosion resistance
C. decreases ductility
D. improves strength and hardness of steel
Explanation: Manganese is added to improve strength and hardness of steel . Based on Manganese content, steel are classified as Carbon Manganese steel (Mn >1%) and Carbon Steel (Mn <1%). If its content exceeds 1.5%, it increases the formation of martensite and hence decreases ductility and toughness.
Which of the following is added to steel to increase resistance to corrosion?
Explanation: Addition of small quantity of copper increases resistance to corrosion. Even Chrome and Nickel are added to impart corrosion resistance property to steel.
CISC is a national industry organization representing the structural steel.
C. Can be yes or no
D. Can not say
Explanation: Yes, CISC is a national industry organization representing the structural steel, open-web steel joist and steel plate fabrication industries in Canada.
