Senior Civil Site Engineer Interview Questions and Answers for Freshers

In the middle of the column

• Bending moment will be zero at the midpoint of a column

• This is because the bending moment is a maximum at the base and decreases linearly towards the top

• At the midpoint, the bending moment changes direction from positive to negative

The self weight of steel depends on its density and volume.

• The self weight of steel is determined by its density, which is typically around 7850 kg/m^3.

• To calculate the self weight of steel, multiply its density by its volume.

• The volume of steel can be calculated by multiplying its length, width, and height.

• For example, if a steel beam has a length of 5 meters, width of 0.3 meters, and height of 0.5 meters, its volume would be 0.075 cubic meters.

• Multiplying the volume by the ...read more

The amount of cement required for one cubic meter of RCC work depends on the mix ratio and design requirements.

• The mix ratio determines the proportion of cement in the concrete mix.

• The design requirements consider factors like strength, durability, and workability.

• The cement quantity can be calculated using the formula: (cement content per unit volume) x (total volume of concrete).

Lapping is not provided at the same point to ensure structural integrity and avoid weak points in the construction.

• Lapping is the overlapping of two reinforcement bars to ensure continuity and strength in the structure.

• Providing lapping at the same point can create a weak point due to the concentration of stress in one area.

• Lapping at different points distributes the load evenly and enhances the overall structural integrity.

• Following proper lapping guidelines as per structura...read more

PCC is provided before foundation to create a level and stable surface for the foundation to be built upon.

• PCC (Plain Cement Concrete) helps in distributing the load of the foundation evenly.

• It prevents direct contact between foundation and soil, reducing the risk of soil erosion.

• PCC provides a smooth and level surface for the foundation to be constructed on, ensuring stability and durability.

• It helps in preventing water from seeping into the foundation, reducing the risk of ...read more
