Kcc Buildcon Bridge Design Engineer Interview Questions and Answers

A foundation is a structural element that supports a building or other structure by transferring its load to the underlying soil or rock.

• Foundations are typically made of concrete, masonry, or steel.

• They are designed to distribute the weight of the structure evenly and prevent settlement or movement.

• Different types of foundations include shallow foundations (such as strip footings and mat foundations) and deep foundati...read more

RCC stands for Reinforced Cement Concrete.

• RCC is a composite material made of cement, sand, aggregates, and steel reinforcement.

• It is widely used in construction for its strength and durability.

• The steel reinforcement provides tensile strength to the concrete, while the cement, sand, and aggregates provide compressive strength.

• RCC is commonly used in the construction of buildings, bridges, dams, and other structures.

• Ex...read more

Cube mould size is a standard size used for testing the compressive strength of concrete.

• Cube moulds are typically made of steel or cast iron.

• The standard size for cube moulds is 150mm x 150mm x 150mm.

• Other sizes such as 100mm x 100mm x 100mm and 200mm x 200mm x 200mm are also used.

• The moulds are filled with concrete and left to cure before being tested for compressive strength.

• Cube moulds are used to ensure that the c...read more

To calculate the weight of an 8mm diameter steel rod, use the formula: weight = volume x density.

• Calculate the volume of the rod using the formula: volume = π x (diameter/2)^2 x length

• Find the density of steel, which is typically around 7850 kg/m^3

• Multiply the volume by the density to get the weight of the rod

Discussion on soil mechanics starting from modulus of elasticity to liquifaction

• Modulus of elasticity is a measure of soil stiffness

• Soil strength is important in determining its ability to withstand loads

• Liquifaction occurs when soil loses strength and behaves like a liquid

• Factors affecting soil strength include soil type, moisture content, and stress history

• Liquifaction can lead to soil failure and damage to structure
