BAR-044 THEORY OF STRUCTURES
Time hours Maximum Marks: 70
Note: Attempt any four questions. Use of scientific calculator and IS 456 code is permitted. Assume any data, if missing, suitably.
1. What do you understand by 'Composite
sections' Give any two examples and write
the advantages of use of such sections. 5
A simply supported RC beam, 300 mm wide
and 500 mm effective depth, carries a
uniformly distributed load -of 50 kN/m
including its own weight over its effective
span of 4 m. Design the shear reinforcement
in the form of vertical stirrups. Use
M 20 grade concrete and Fe 415 grade steel.
Use working stress method of design.
Assume that the beam contains
reinforcement throughout its length.
2. Discuss why over-reinforced RC beam sections are to be avoided. What should be the remedy? 5
Determine the moment of resistance of a singly reinforced RC beam, 160 mm wide and 300 mm deep to the centre of reinforcement. The reinforcement consists of 4 bars of 16 mm diameter. Use M 20 grade 1 concrete and Fe 415 grade steel. 12 1/2
3. Compare the load transfer mechanism in one-way and two-way slabs. Provide neat sketches showing load transfer III both cases, if a concentrated load is applied at the centre of the slabs. 5
A reinforced concrete column, 4 m effective length and 400 mm in diameter, is reinforced with 8 bars of 20 mm diameter. Find the safe load for the column. The column is provided with lateral ties. Use 1M 25 grade concrete and Fe 415 grade steel. 12 1/2
4. Discuss why shear reinforcement is usually not required in slabs of residential buildings unlike in RC beams. 5 Design an isolated footing of uniform thickness for a reinforced concrete column bearing an axial load of 600 kN. The size of the column is 300 rom x 300 mm. The safe bearing capacity of soil may be taken as 120 kN/m2 . Use M 20 grade concrete and Fe 415 grade steel. Take the total thickness of footing as 400 mm. Draw a neat sketch showing the detailing of reinforcement. 12 1/2
5. Enlist the various types of foundations and provide a neat sketch of anyone type. 5
Design the cantilever chajja slab, shown in Figure 1. Take live load intensity on the slab as 2 kN/m2 . Use M 20 grade concrete and Fe 415 grade steel. 12 1/2

6. Differentiate between earthquake-resistant and earthquake-proof structures. 5
Discuss various practices which help us make earthquake-resistant structures. Provide neat sketches in your answer. 12 1/2
7. Write short notes on the following:
Classification of different types of columns 5 1/2
Precautions to be taken for quality control in concrete construction 6 Utility of thumb rules in design 6
