Tecnimont 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

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

• I have experience with retaining walls, foundations, and underground parking structures.

• I have worked on projects involving deep excavations and shoring system...read more

Earthquake loads are calculated using seismic design codes and formulas based on the seismic hazard of the region.

• Determine the seismic hazard of the region using historical data and seismic maps

• Select a seismic design code such as ASCE 7 or Eurocode 8

• Calculate the seismic base shear using the formula V = CsW

• Distribute the seismic base shear to the structure using the appropriate load combinations

• Consider the effects o...read more
