B E Civil Engineer Interview Questions and Answers

Bent up bars are reinforcement bars that are bent at the ends to provide additional anchorage in concrete structures.

• Bent up bars are commonly used in beams and slabs to resist tension forces.

• They are bent at a certain angle to ensure proper anchorage and prevent slipping.

• The formula for calculating steel reinforcement in concrete structures is typically based on the design requirements and load conditions.

• Common formulas in civil engineering include those for calculating ben...read more

Angle for hook at stirrups is typically 135 degrees. Minimum cover for column beam is 25mm. Ld refers to live load.

• Angle for hook at stirrups is usually 135 degrees for proper anchorage

• Minimum cover for column beam is typically 25mm to protect reinforcement from corrosion

• Ld in civil engineering refers to live load on the structure

The weight of a 32 mm diameter bar can be calculated using the formula for the weight of a round bar.

• Calculate the cross-sectional area of the bar using the formula A = πr^2, where r is the radius (diameter/2)

• Determine the weight of the bar using the formula Weight = Volume x Density, where Volume = A x Length and Density is the density of the material

• For example, for a steel bar with a density of 7850 kg/m^3 and a length of 1 meter, the weight of a 32 mm diameter bar would b...read more

Stressing calculation involves determining the internal forces acting on a structure and analyzing their effects.

• Calculate the external loads acting on the structure

• Determine the support reactions at the foundation

• Analyze the internal forces using methods like the method of joints or sections

• Calculate the stresses in the structural members based on the internal forces

• Consider factors like material properties and safety factors in the calculations

Managing vendors involves communication, negotiation, and relationship building.

• Establish clear expectations and requirements

• Communicate regularly to ensure alignment

• Negotiate terms and pricing to achieve mutual benefit

• Build strong relationships based on trust and respect

• Monitor performance and provide feedback for improvement

• Resolve conflicts promptly and professionally

LD stands for Line of Development, which is a line connecting the points of intersection of the ground surface and the tunnel axis.

• LD is used in tunneling projects to determine the alignment of the tunnel with respect to the ground surface.

• It helps in ensuring that the tunnel is constructed in the desired direction and at the correct depth.

• LD is crucial for maintaining the stability and structural integrity of the tunnel.

• Example: In a subway construction project, LD is used t...read more
