STRUCTURAL ANALYSIS-I (Civil Engineering)Time: 3 hours Max. Marks: 70
Note: 1. Question Paper consists of two parts (Part-A and Part-B) 2. Answer ALL the question in Part-A
3. Answer any THREE Questions from Part-B
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
PART ?A
1. a) Define deflection
b) Write about sinking of support
c) Write moment of inertia for I Section
d) Write the formula for slope for a cantilever beam with point load at end
e) Draw bending moment diagram for simply supported beam with point load at
centre
f) Define influence line
PART -B
2. Draw the bending moment and shear force diagram of a propped cantilever beam
of span 6m due to a point load of 6 kN at the mid span.
3. Find the fixed end moments for a fixed beam of span 6 m subjected to a
concentrated clockwise moment of 10 kNm at 2.5 m from the left end

4. A continuous beam ABC consists of spans AB and BC of lengths 4m and 6m
respectively, the ends A and B being fixed. C is a free end. The span AB carries a
uniformly distributed load of 24 kN/m while the span BC carries a point load of
108 kN at a distance of 2m from C. Find the support moments and support
reactions

5.
A simply supported beam of span 6m is subjected to a concentrated load of 45 KN
at 2m from the left support. Calculate the deflection under the load point. Take E =
200 x 10

.

6. Define Strain energy. Derive an expression for strain energy due to bending
moment.

7. Draw the influence line diagram for B.M at a point 8m from the left abutment on a
bridge girder of span 30m and find the maximum B.M at that point due to a series
of wheel loads 80kN, 160kN, 160kN and 160kN at centre to centre distances of
4m, 2.5m, 2.5m and 2.5m respectively. The loads can cross in either directions
