Sample FOUNDATION ENGINEERING Important Questions CE6502 :

1.DEFINE END BEARING PILE

End bearing piles are used to transfer load through water or soft soil to a suitable bearing stratum. The end bearing pile is driven through poor soil strata and rests on a firm incompressible stratum such as rock, developing the bearing pressure of its base and passing it to that firm stratum.

2. Define group efficiency of pile.

The ratio of resting capacity of a pile group to the sum of individual capacities of piles in the group is termed as group efficiency.
Group efficiency

3. List out the type of pile based on material used? (FOUNDATION ENGINEERING Important Questions)

 Timber pile,
 Concrete pile,
 Steel pile,
 Composite pile

4. How is the selection of pile carried out?

The selection of the type, length and capacity is usually made from estimation based on the soil condition and magnitude of the load.

5. What is mean by group settlement ratio? (FOUNDATION ENGINEERING Important Questions)

The settlement of pile group is found to be many times that of a single pile. The ratio of the settlement of the pile group to that of a single pile is known as the group settlement ratio.

6. What are the factors consider while selecting the type of pile?
 The loads
 Time available for completion of the job
 Availability of equipment
 The ground water conditions
 The characteristics of the soil strata involved

Sample Structural Analysis 1 Important questions CE6501:

1. Why is it necessary to compute deflections in structures?

Computation of deflection of structures is necessary for the following reasons:
a. If the deflection of a structure is more than the permissible, the structure will not look
aesthetic and will cause psychological upsetting of the occupants.
b. Exessive deflection may cause cracking in the materials attached to the structure. For
example, if the deflection of a floor beam is excessive, the floor finishes and partition
walls supported on the beam may get cracked and unserviceable.

2. What is meant by cambering technique in structures? (Structural Analysis 1 Important questions)

Cambering is a technique applied on site, in which a slight upward curve is made in the structure/beam during construction, so that it will straighten out and attain the straight shape during loading. This will considerably reduce the downward deflection that may occur at later
stages.

3. Name any four methods used for computation of deflections in structures.(Structural Analysis 1 Important questions)

• Double integration method
• Macaulay‟s method
• Conjugate beam method
• Moment area method
• Method of elastic weights
• Virtual work method- Dummy unit load method
• Strain energy method
• Williot Mohr diagram method

4. State the difference between strain energy method and unit load method in the determination of deflection of structures. (Structural Analysis 1 Important questions)

In strain energy method, an imaginary load P is applied at the point where the deflection is desired to be determined. P is equated to zero in the final step and the deflection is obtained. In unit load method, an unit load (instead of P) is applied at the point where the deflection is desired.

5. What are the assumptions made in the unit load method?

• The external & internal forces are in equilibrium.
• Supports are rigid and no movement is possible.
• The materials is strained well with in the elastic limit.

Surveying 1 Important Questions CE6304

Surveying 1 Important Questions REGULATION 2013 ANNA UNIVERSITY free download. CE6304 Important Questions free download. Surveying 1 Regulation 2013 pdf free

Sample Surveying 1 Important Questions:

1. Define Surveying. What are the fundamental p rinciples of surveying?

Surveying is an art of determining the relative positions of various points on, above or below the surface of the earth by means of direct or indirect measurement of distance, direction and elevation.

The principles of surveying are:
(i) Working from whole to part.
(ii)To locate a new station by at least two measurements (angular, linear) from fixed reference points.

2. What is the object or purpose of surveying?

The primary object of surveying is to prepare a plan or map to show the relative position of
the objects on the surface of the earth. It is also used to determine the areas, volumes and other related
quantities.

3. Name the different ways of classification of surveys. (Surveying 1 Important Questions)

a. Primary classification
(i). Plane surveying (ii). Geodetic surveying.
b.Secondary classification
(i). Based on instruments used (ii).Based on methods.
(iii). Based on object (iv). Based on nature of the field

5. Define the constructions of a diagonal scale.

For a given short length ( PQ=PR), draw a right angle triangle. Its base( PR) and height (PQ) are equal. A short length is divided into a number of parts by using the principle of similar triangles in which like sides are proportional. Thus, 1-1 represents 1/ 10 PQ9-9 represents 9/ 10 PQ

6. Define chain surveying. What is the fundamental principle of chain surveying? (Surveying 1 Important Questions)

Chain surveying is the type of surveying in which only linear measurements are made in the field. The main principle of chain surveying or chain triangulation is to provide a framework
consist of number of well-conditioned triangles or nearly equilateral triangles. It is used to find the area of the field.

7. What is a well-conditioned triangle? What is its specific advantage?

A triangle is said to be well- conditioned or well proportioned when it contains no angle smaller than 300 and no angle greater than 1200.The main principle of chain surveying is chain triangulation. It consists of frame work of triangles. To plot the network of triangles accurately, the triangles must be nearly equal to equilateral or well-conditioned. The distortion due to errors in measurement and plotting should be minimum.
