OVERVIEW OF CIVIL ENGINEERING

 

I. Answer the following:

1. Brief on the specialized sub-disciplines in civil engineering.

2. Give an overview of the contributions of a civil engineer to the welfare of the society.

3. Discuss the classification of external forces acting on a structure. Give examples.

4. Explain the basic types of stress and strain with necessary equations.

5. Draw the stress-strain curve of mild steel. Explain the salient points on it.

6. A member AC of a truss carries a tensile force of 63 kN and a member BD carries a compressive force of 54 kN. The cross sectional area of each member is 900 mm. Calculate the stresses in the members.

Solution

For member AC

7. A hollow steel column carries a load of 1200 kN. Compute the external diameter of the column if the internal diameter is 150 mm and the ultimate stress is 450 N/mm2. Adopt a factor of safety of 4.

 Solution

8. A vertical square bar of length 500 mm and size 100 mm x 100 mm is fixed at its base and free at its top. A horizontal force of 900 kN is acting at its top. This force causes a horizontal distortion of 5.5 mm at top. Determine the shear stress in MPA and shear strain in terms of angle of distortion (radian).

9. A square masonry column of size 200 mm has to be replaced by a circular solid timber column. If the allowable stress in the masonry is 5 N/mm2 and allowable stress in timber is 8 N/mm2, calculate the diameter of the timber column.

10. A bar of 30 mm diameter is subjected to a pull of 60 kN. The measured extension on a gauge length of 200 mm is 0.1 mm. The change in diameter is 0.004 mm. Calculate the Young's Modulus, Poisson's Ratio, Bulk Modulus and Change in Volume of the bar.

11. A R.C.C. Column of square cross-section of size 500 mm x 500 mm and 3.3 meters height carries a load of 1000 kN. It is reinforced with 4 steel bars of 25 mm diameter. Young's Modulus of concrete is 0.14 x 105 N/mm2 and Young's Modulus of steel is 2.1 x 105 N/mm2. Compute the stresses to which concrete and steel bars are subjected to

12. Explain the basic types of stress and strain acting in structures.

13. Explain stress – strain diagram for mild steel and the properties that can be obtained.
