1. What is the primary reason for using steel in construction?
Answer:
Explanation:
Steel is favored in construction for its high strength-to-weight ratio, which allows for the building of large structures with less material weight.
2. Which type of steel structure is commonly used in skyscrapers?
Answer:
Explanation:
Structural steel framing is commonly used in skyscrapers due to its strength, flexibility, and speed of construction.
3. What does the term 'buckling' refer to in steel structures?
Answer:
Explanation:
Buckling is the failure mode of a structural element subjected to high compressive stress, leading to a sudden sideways deflection.
4. In steel design, what does the term 'yield strength' signify?
Answer:
Explanation:
Yield strength is the amount of stress at which a material will deform permanently. This is a critical property for designing steel structures.
5. What is the main purpose of providing bracings in steel structures?
Answer:
Explanation:
Bracings in steel structures are used to resist lateral loads such as wind or seismic forces, providing stability to the structure.
6. The term 'fabrication' in steel construction refers to:
Answer:
Explanation:
Fabrication is the process where steel components are cut, bent, and assembled to form structural elements before being transported to the site.
7. What role do web plates play in a steel I-beam?
Answer:
Explanation:
The web plate of an I-beam resists shear forces, while the flanges resist most of the bending moment.
8. In steel design, what is the purpose of a 'gusset plate'?
Answer:
Explanation:
Gusset plates are used in steel construction to connect beams and columns. They help in distributing the load and providing stability to the joint.
9. What is the common method for protecting steel structures from corrosion?
Answer:
Explanation:
Protective coatings, such as paint or galvanizing, are commonly used to protect steel structures from corrosion.
10. The term 'flange' in a steel beam refers to:
Answer:
Explanation:
In a steel beam, the flanges are the horizontal elements at the top and bottom, which primarily resist the bending moments.
11. Which type of steel connection is designed to allow for movement due to thermal expansion?
Answer:
Explanation:
Sliding connections are designed to accommodate movement, such as thermal expansion and contraction in steel structures.
12. In steel structures, what does the term 'fireproofing' mean?
Answer:
Explanation:
Fireproofing in steel structures involves applying materials that prevent or slow down the increase in temperature of the steel during a fire.
13. The process of joining steel components using heat is known as:
Answer:
Explanation:
Welding is a process where steel components are joined together using heat and/or pressure to form a continuous bond.
14. Why are hollow steel sections often used in construction?
Answer:
Explanation:
Hollow steel sections offer a high strength-to-weight ratio, making them efficient for use in various structural applications.
15. In steel design, the term 'plastic analysis' refers to:
Answer:
Explanation:
Plastic analysis is a design method that allows for the redistribution of moments and loads in steel structures, taking into account the material's ability to undergo significant plastic deformation before failure.
16. The primary function of a steel column in a structure is to:
Answer:
Explanation:
The primary function of a steel column in a structure is to support vertical loads, transferring them to the foundation.
17. A 'moment connection' in steel structures is used to:
Answer:
Explanation:
A moment connection in steel structures is designed to resist rotational forces and moments, ensuring the continuity of the frame.
18. The term 'live load' in steel structure design refers to:
Answer:
Explanation:
Live loads are temporary loads that are not permanently attached to the structure, such as people, furniture, and vehicles.
19. What is the primary purpose of lateral bracing in steel beams?
Answer:
Explanation:
Lateral bracing in steel beams is provided to prevent lateral torsional buckling, ensuring stability under load.
20. The term 'elastic limit' in steel design refers to:
Answer:
Explanation:
The elastic limit is the maximum stress that a material can withstand without undergoing permanent deformation.
21. Why is detailing important in steel structure design?
Answer:
Explanation:
Detailing in steel structure design is crucial for ensuring the correct fit, alignment, and assembly of various components, thereby ensuring structural integrity and functionality.
22. In steel structures, 'fatigue' refers to:
Answer:
Explanation:
Fatigue in steel structures is the weakening or failure of material due to repeated or fluctuating stresses.
23. A 'base plate' in steel construction is used to:
Answer:
Explanation:
A base plate is used in steel construction to connect the bottom of the steel column to the foundation, ensuring load transfer and stability.
24. In steel structures, shear connectors are used to:
Answer:
Explanation:
Shear connectors are used in composite construction, such as in steel-concrete composite beams, to ensure that the steel beam and concrete slab act together under load.
25. The main reason for providing stiffeners in a steel plate girder is to:
Answer:
Explanation:
Stiffeners are provided in steel plate girders to prevent local buckling of the web due to shear forces, thus enhancing the strength and stability of the girder.
