BAR-034 THEORY OF STRUCTURES -IV
Time hours Maximum Marks: 70
Note: Question no. 1 is compulsory. Answer any four questions from the remaining questions. Use of IS 800 and steel tables is permitted. Assume any missing data suitably.
1. Choose the most appropriate answer from the options given in questions to below: 7x2=14 Which of the following supports may produce six reactions in a space structure? Roller support
(ii) Pinned support
(iii) Hinged support
(iv) Fixed support Indeterminacy of a cantilever beam, propped at free end with a roller support, is 1
(ii) 2
(iii) 3
(iv) 4
(c) Which of the following may be a unit of stiffness? N mm^2
(ii) N mm
(iii) N/mm
(iv) N/mm^2 The flexural stiffness of a beam is EI
(ii) EI^2
(iii) E^2I
(iv) I/EI
where E and I have their usual meanings. Which of the following is the most ductile material? Mild steel
(ii) Concrete
(iii) Medium tensile steel
(iv) Brick Choose the correct statement. Plain concrete should be used to construct beams.
(ii) Columns can never be subjected to shear forces
(iii) Indeterminacy of a simply supported beam is 3.
(iv) Structures should be stable. The shape of BMD for a cantilever for a point load at free end is Triangular
(ii) Parabolic
(iii) Rectangular
(iv) None of the above
2. What is meant by a determinate structure? Discuss briefly with an example. 7 Describe the characteristics of.a post and lintel system in brief. 7
3. Analyse the structure shown in Figure 1 by Moment Distribution method and draw the BMD. <img src='./qimages/8289-3.jpg'>
Moment of intertia values for spans are shown encircled in the figure. Young's modulus of elasticity for the beam material may be taken as E uniformly. 14
4. What are portal frames? How do they resist horizontal forces Discuss in short. 7 Compare the working of an arch and a beam briefly. 7
5. Compare bolted and welded steel connections. 7 Draw stress-strain curves of mild steel and high strength steel and briefly compare them. 7
6. Provide a classification of welds. Draw neat sketches for various types of welds. 7 Explain the meaning of 'size of weld' and 'throat thickness of weld' with the help of a neat sketch. 7
7. Write short notes on any two of the following: 2x7=14
Three-hinged arch Characteristics of a fixed support Shear force diagram Design of steel girders
