10+ Unirac Interview Questions and Answers

Extra bars in beams should be provided at locations of high bending moments or where additional reinforcement is required.

• Extra bars should be provided at supports and near the mid-span of the beam where bending moments are highest.

• Additional reinforcement may be required at locations where concentrated loads or point loads are applied.

• Extra bars should also be provided at locations where there are openings or cutouts in the beam.

• In seismic zones, extra bars should be provide...read more

Extra bars in beams are used to increase the strength and load-bearing capacity of the structure.

• Extra bars, also known as reinforcement bars or rebar, are added to beams to enhance their structural integrity.

• These bars are typically made of steel and are placed within the concrete to provide additional strength.

• The purpose of extra bars is to resist tensile forces and prevent cracking or failure of the beam under heavy loads.

• They help distribute the load evenly across the be...read more

To convert from cubic feet to cubic meters, multiply the value in cubic feet by 0.0283168466.

• Multiply the value in cubic feet by 0.0283168466 to get the equivalent in cubic meters.

• For example, if you have 100 cubic feet, multiply 100 by 0.0283168466 to get 2.83168466 cubic meters.

• Remember to use the correct conversion factor when converting between different units of volume.

The M20 grade concrete mix ratio is 1:1.5:3, which means 1 part cement, 1.5 parts sand, and 3 parts aggregate.

• M20 grade concrete is commonly used for general construction purposes.

• The mix ratio of M20 grade concrete is 1:1.5:3, which indicates the proportion of cement, sand, and aggregate respectively.

• For example, if we need to prepare 1 cubic meter of M20 grade concrete, we would need 1 part cement, 1.5 parts sand, and 3 parts aggregate.

Cranks are provided in slabs to resist the bending moments and shear forces.

• Cranks help in distributing the load uniformly across the slab.

• They increase the load-carrying capacity of the slab.

• Cranks prevent the formation of cracks and improve the overall structural integrity.

• They help in reducing the deflection of the slab.

• Cranks are especially useful in areas where heavy loads or concentrated loads are expected, such as near columns or walls.

• By providing cranks, the slab bec...read more

The minimum and maximum slope depend on the purpose of the site and the type of terrain.

• The minimum slope for a site is typically 0.5% to ensure proper drainage.

• The maximum slope depends on the type of terrain and the intended use of the site.

• For example, a road can have a maximum slope of 10% while a pedestrian walkway can have a maximum slope of 5%.

• In some cases, steep slopes may require retaining walls or other stabilization measures.

• The slope should be designed to ensure ...read more

M25 Grade concrete is a type of concrete with a compressive strength of 25 megapascals (MPa).

• M25 Grade concrete is commonly used in construction projects.

• It is a mix of cement, sand, and coarse aggregates in a specific ratio.

• The ratio of cement to sand to coarse aggregates in M25 Grade concrete is 1:1:2.

• The water-cement ratio for M25 Grade concrete is typically 0.45.

• M25 Grade concrete has a compressive strength of 25 MPa after 28 days of curing.

To convert from meters to feet, multiply the value in meters by 3.281.

• Multiply the value in meters by 3.281 to get the value in feet.

• For example, 10 meters is equal to 32.81 feet.

• Remember to use the correct unit abbreviation when writing the answer, i.e. ft for feet.

The units of load in civil engineering are typically measured in force per unit area.

• Units of load include pounds per square inch (psi), kilonewtons per square meter (kPa), and tons per square foot.

• Load can also be measured in terms of distributed load or concentrated load.

• Examples of distributed load units include pounds per linear foot (plf) or kilonewtons per meter (kN/m).

• Examples of concentrated load units include pounds (lb) or kilonewtons (kN).
