B. G. Shirke Construction Technology Structural Design Engineer Interview Questions and Answers

Favourable zone in RCC refers to the region of a reinforced concrete member where the concrete is in compression and the steel is in tension.

• Favourable zone is the area where the concrete is able to resist compressive forces effectively.

• It is typically located at the top of a beam or slab, where the bending moment is highest.

• In this zone, the steel reinforcement helps to resist tensile forces, while the concrete resist...read more

Lap length is the length of overlap between two reinforcing bars in a concrete structure to ensure proper transfer of loads.

• Lap length is important for ensuring the continuity of reinforcement in concrete structures.

• It is typically specified in building codes and design standards.

• The lap length required depends on factors such as the diameter of the bars, concrete strength, and design loads.

• For example, in a beam, the ...read more

Lapping in reinforcement involves overlapping two reinforcement bars to ensure continuity and strength in the structure.

• Lapping is commonly used in construction to connect two reinforcement bars together.

• The length of the lap varies depending on the design requirements and the type of reinforcement used.

• Proper lapping ensures that the load is transferred effectively between the bars.

• Examples of lapping include lap spli

Bearings in bridges help distribute loads and allow for movement due to temperature changes and settlement.

• Bearings help distribute the loads from the superstructure to the substructure of the bridge.

• They allow for movement of the bridge deck due to temperature changes, wind forces, and settlement of the foundation.

• Bearings help reduce stress on the bridge components and prevent damage.

• Common types of bearings used in ...read more

Types of expansion joints include slip joints, bellows joints, and modular joints.

• Slip joints allow for movement in one direction only

• Bellows joints accommodate movement in multiple directions

• Modular joints are made up of separate components that can be replaced individually

Static analysis deals with loads that do not change over time, while dynamic analysis considers loads that vary with time.

• Static analysis is used to determine the effects of loads that do not change over time, such as dead loads and live loads.

• Dynamic analysis considers loads that vary with time, such as wind loads, seismic loads, and vibrations.

• Static analysis is simpler and less computationally intensive compared to ...read more

Spectral fatigue analysis is performed by calculating the stress response of a structure to dynamic loads over a range of frequencies.

• Determine the dynamic loads acting on the structure

• Calculate the stress response of the structure using spectral methods

• Analyze the stress response at different frequencies to assess fatigue damage

• Consider factors such as material properties, load history, and environmental conditions

• Use...read more

I prioritize transparency, disclose the conflict, and recuse myself if necessary.

• Prioritize transparency and disclose the conflict to all parties involved

• Evaluate the situation and determine if recusal is necessary

• Seek guidance from a supervisor or ethics committee if unsure how to proceed

My notice period is currently one month.

• Notice period is one month

• I am required to give one month notice before leaving my current position

• I can start a new position after one month

Fixed connection does not allow rotation at the base plate, while pinned connection allows rotation.

• Fixed connection is rigid and does not allow rotation at the base plate.

• Pinned connection allows rotation at the base plate.

• Fixed connection provides more stability and resistance to lateral forces.

• Pinned connection is more flexible and allows for some movement.

• Examples: Fixed connection is commonly used in high-rise bui...read more

The rise is the vertical distance between two consecutive steps, while the tread is the horizontal distance.

• The rise is typically around 7-8 inches, while the tread is usually around 10-11 inches.

• The rise and tread dimensions are important for ensuring safe and comfortable stair design.

• Building codes often dictate the minimum and maximum rise and tread dimensions for safety reasons.

Pitch distance in bolt refers to the distance between the centers of adjacent bolts in a bolted connection.

• Pitch distance is typically measured from the center of one bolt to the center of the next bolt in a row.

• It is important to maintain consistent pitch distances to ensure proper load distribution and structural integrity.

• For example, in a bolted connection with a pitch distance of 2 inches, the centers of adjacent

To create a pipe rack section on both directions.

• Identify the location and dimensions for the pipe rack section

• Consider the load requirements and support structures

• Design the pipe rack section using appropriate materials and connections

• Ensure proper spacing and alignment for pipes in both directions

Yes, I have extensive experience with basements and below ground structures.
