# Civil Engineering Interview Questions and Answers

Civil Engineering is a branch of engineering which deals with building, long stories, their designing, constructions, and maintenance with the passing time. With the advancement in the number of job opportunities, there has been a rise in the number of **Civil Engineering Interview Questions**. It is a discipline which involves the construction of public works, namely sewerage systems, roads, canals, structural components of buildings.

### Most Frequently Asked Civil Engineering Interview Questions

**Civil Engineering** is dealing with construction, design, and maintenance of the environment be it natural or built by them. It is a professional discipline of engineering which focuses on constructing airports, bridges, dams and airports, structural components. There are many more on the list such as railways, roads, etc.

There are various sub-disciplines of civil engineering and takes the second place in the list of the age of engineering, at first place comes military engineering.

Give an accurate answer to the above **civil engineering** interview question and score high.

AutoCAD and 3D Max are the most popular software used in Civil Engineering. These are helpful in making various high-tech presentations, reports, billing purposes. All the designs, modeling, design, architectural drawing, Auto-desk 2D and 3D designs can be successfully made with the help of this two software.

To find the weight of the concrete, multiply the length, height, and width of the area where the concrete is to be filled. Then you will get the volume of the place or the volume of the concrete to be used. To get the weight of the concrete in pounds, multiply the volume which we have got in cubic feet by 143.38 pounds/feet^3.

Per cubic meter, the unit weight of steel is 7850 kgs. In pounds per cubic foot, it is 489.8 pounds. It totally depends on the exact composition of the steel as it is an alloy of carbon and iron.

S.no | Beam | Slab |
---|---|---|

1. | It is a linear structural element where perpendicular loads known as flex load are applied along with the axis. | It is a flexural component that distributes the load horizontally to one or more directions within a single plane. |

2. | A beam is the most common example of a structural element in bending | While the resistance to bending of a slab is similar to that of a beam, it differs from that of a comparable series of independent beams in continuity in both directions. |

3. | It is the most direct solution to the most common structural problems of transferring horizontal loads of gravity to the load elements. | A slab is used when concentrated loads result in a perpendicular bending located in the first direction of extension causing torsion in the slab. |

S.no | One-way slab | Two-way slab |
---|---|---|

1. | The beams support the one-way slab on the two opposite sides. The main purpose is carrying the load along one direction. | In two-way slab, beams support the loads and four sides of the concrete slab along with both the directions. |

2. | The ratio of the longer span to shorter span is equal or greater than 2. | The ratio of the longer span to shorter span is less than 2. |

3. | Example- Verandah Slab | Example- Multi-storey buildings |

Minimum length of a crank is 300 mm.

The formula of Crank length = (d1+d2+5) *10mm where d1 is the diameter of smaller bar and d2 is the diameter of the largest bar.

Also, the slope of the crank is 1:10 (one of the common civil engineering interview questions.)

The cement’s strength is tested on hardened Cement-Sand mortar’s cubes, and these are prepared out of the cement which has a strength of 53MPa. It is derived from 53 Grade OPC Cement giving 28-days of compressive strength of the cement. It is one of the most common civil engineering interview questions.

#### Development History

In the year 1819, Norwich University became the first college to teach Civil Engineering. Read **Civil Engineering Interview Questions** below. In the year 1835, Rensselaer Polytechnic Institute awarded the first civil engineering degree.

#### Advantages

- Being a civil engineer, you get several opportunities for meeting a lot of work, people and interact with people.
- Helps in gaining appropriate skills required for a better client dealing
- Civil Engineering gives a structure to perform all the activities to be done in an organized way.
