Apco Infratech Senior Structural Engineer Interview Questions, Process, and Tips

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
