Questions and Answers
  • 1. 

    What is Butt weld specified by?

    • A.

      Leg length

    • B.

      Effective throat thickness

    • C.

      Plate thickness

    • D.

      None of these

    Correct Answer
    B. Effective throat thickness
    Explanation
    Butt weld is specified by the effective throat thickness, which refers to the minimum distance from the root of the weld to the face of the weld. This measurement is important in determining the strength and integrity of the weld joint. The leg length, on the other hand, refers to the distance from the root to the toe of the weld, and the plate thickness is simply the thickness of the material being welded. Therefore, neither the leg length nor the plate thickness is the correct specification for butt weld.

    Steel design is a branch of

    • A.

      Structural engineering

    • B.

      Chemical engineering

    • C.

      Mechanical engineering

    • D.

      None of these

    Correct Answer
    A. Structural engineering
    Explanation
    Steel design is a branch of structural engineering because it involves the analysis and design of steel structures such as buildings, bridges, and towers. Structural engineering specifically focuses on the design and construction of structures to withstand loads and forces, ensuring their stability and safety. Steel is a commonly used material in structural engineering due to its high strength and durability. Therefore, steel design falls under the domain of structural engineering rather than chemical engineering or mechanical engineering.

    What may cause the failure of a rivet joint?

    • A.

      Shear failure of rivets

    • B.

      Bearing failure of rivets

    • C.

      Tearing failure of plates

    • D.

      All of these

    Correct Answer
    D. All of these
    Explanation
    The failure of a rivet joint can be caused by shear failure of the rivets, bearing failure of the rivets, or tearing failure of the plates. Shear failure occurs when the rivets are subjected to forces that exceed their shear strength, causing them to break. Bearing failure happens when the rivets are subjected to compressive forces that exceed their bearing strength, leading to deformation or crushing of the rivets. Tearing failure occurs when the plates connected by the rivets experience excessive tensile forces, causing them to tear apart. Therefore, all of these factors can contribute to the failure of a rivet joint.

    This one is the best compression member section.

    • A.

      I-section

    • B.

      Double angle section

    • C.

      Single angle section

    • D.

      Tubular section

    Correct Answer
    D. Tubular section
    Explanation
    A tubular section is considered the best compression member section because it offers high strength and stiffness while using less material compared to other sections. The hollow shape of a tubular section allows for efficient distribution of forces and provides resistance against buckling and bending. This makes it ideal for applications where compression loads need to be supported, such as in columns or structural supports. Additionally, the tubular section has a symmetrical design, which simplifies its fabrication and connection to other structural elements.

    What is an ideal compression section?

    • A.

      One with the same amount of inertia about any axis through its center of gravity

    • B.

      One with a different amount of inertias about any axis through its center of gravity

    • C.

      One with a mostly uneven amount of inertia about any axis through its center of gravity

    • D.

      None of these

    Correct Answer
    A. One with the same amount of inertia about any axis through its center of gravity
    Explanation
    An ideal compression section is one that has the same amount of inertia about any axis through its center of gravity. This means that the section is symmetrical and balanced, allowing for uniform distribution of forces during compression. Having the same amount of inertia about any axis through its center of gravity ensures that the section will experience equal resistance to deformation in all directions, making it ideal for compression.

    The portal frame is known as

    • A.

      The least used type of light steel structure

    • B.

      The most complex type of light steel structure

    • C.

      The most common type of light steel structure

    • D.

      None of these

    Correct Answer
    C. The most common type of light steel structure
    Explanation
    The correct answer is "The most common type of light steel structure." This is because portal frames are widely used in construction due to their simplicity, efficiency, and cost-effectiveness. They consist of columns and beams connected by rigid joints, forming a rigid frame that can withstand heavy loads and provide stability to the structure. Portal frames are commonly used in industrial buildings, warehouses, and agricultural structures.

    Which of these is an advantage of steel structures?

    • A.

      Mass production

    • B.

      Prefabrication

    • C.

      Both A & B

    • D.

      None of these

    Correct Answer
    C. Both A & B
    Explanation
    Both mass production and prefabrication are advantages of steel structures. Mass production refers to the ability to produce large quantities of steel components quickly and efficiently, reducing costs and construction time. Prefabrication involves manufacturing steel components off-site and then assembling them at the construction site, which increases efficiency and quality control. Therefore, both A (mass production) and B (prefabrication) are advantages of steel structures.

    Which of these is not a method for the design of steel structures?

    • A.

      Opened design

    • B.

      Simple design

    • C.

      Continuous design

    • D.

      All of these

    Correct Answer
    A. Opened design
    Explanation
    Opened design is not a method for the design of steel structures. The other options - simple design and continuous design - are valid methods used in the design of steel structures. Opened design is not a recognized or commonly used approach in the field of steel structure design.

    The earthquake load is a

    • A.

      Narrowed-down load

    • B.

      Simple load

    • C.

      Ultimate load

    • D.

      Dynamic load

    Correct Answer
    D. Dynamic load
    Explanation
    The correct answer is "Dynamic load" because earthquakes generate a dynamic force that causes the ground to shake. This shaking motion transfers energy to structures, resulting in dynamic loads. Unlike static loads, which are constant and do not change over time, dynamic loads vary in magnitude and direction during an earthquake event. Therefore, the earthquake load is considered a dynamic load.

    Which is the best method for the design of steel structures?

    • A.

      Earthquake load method

    • B.

      Limit state method

    • C.

      Ultimate load method

    • D.

      None of these

    Correct Answer
    B. Limit state method
    Explanation
    The limit state method is considered the best method for the design of steel structures because it takes into account both the ultimate strength and the serviceability requirements. This method ensures that the structure can withstand all the possible loads and environmental conditions it may encounter throughout its design life. It provides a more comprehensive and reliable approach to design, considering factors such as strength, stability, durability, and deformations. This method also allows for a more efficient use of materials, resulting in cost-effective and safe steel structures.
