Course Name: THEORY OF STRUCTURES III
Max. Marks: 60 Duration: 3 Hours
PART A
Answer all questions, each carries 4 marks. Marks
1 Explain the term torsional rigidity. (4)
2 Explain the term slenderness ratio and discuss the failure of long column. (4)
3 Explain the steps involved in the consistent deformation method. (4)
4 Write the steps involved in analysis of continuous beam by three moment theorem (4)
with support settlement.
5 Differentiate between sway and non sway frames with sketches. (4)
PART B
Answer any two questions, each carries 10 marks.
6 A beam of length 6m is simply supported at its ends and carries two point load of
50KN and 40KN at a distance of 1m and 3m respectively from the left support. Find
by conjugate beam method
1) Deflection under each load (7)
2) Slope at supports (3)
5
E=2X10 N/mm2 and I= 85X106 mm4
7 A rolled beam section has overall depth of 400mm and flange width of (10)
200mm.Thickness of web and flange is 20mm.When it is used as a simply
supported beam produces a mid span deflection 10mm due to a uniformly
distributed load of 30kN/m. Find crippling load when this section is used as column
with both ends hinged. Take E=2 X 10 5 N/mm2.
