INSTRUCTION TO CANDIDATES :
1. Attempt any FIVE questions out of EIGHT questions.
2. Each question carries TWENTY marks.
3. Any missing data may be assumed appropriately.

1. a) What are the factors to be considered in the selection of a suitable bridge site?
b) How we do the choice of a bridge type?
2. a) Explain impact effect for IRC class A or B loading and for IRC class AA loading.
b) What are the four standard types of live load considered in the code? Explain them in
detail.
3. a) How does a finite difference method differ from finite element method?
b) Explain different types of expansion bearings used in girder bridges.
4. a) Differentiate abutment and pier. Enlist various forces which a designer must consider
during analysis of these elements.
b) Differentiate well foundation and caisson foundation. Discuss cases where each of
these two types of foundations are suitable.
5. a) Describe Courbon?s Method of loading in detail with the help of suitable example.
b) Write a short note on eraction of bridge super structure.
6. A group of nine friction piles of 200 mm diameter spaced at 0.5 m transfer a load of
400 kN into a 10 m thick clay layer with sand below. It penetrates to a depth of 6 m in the
clay layer. Estimate the probable settlement of the pile group. Assuming water table is at
ground level. Take water content = 39%, G = 2.7 and ?
sat
= 20 kN/m
