IS 456 2000 and SP 16 Charts are Permitted
UNIT I
1. Write the assumptions in limit state of collapse in flexure.
Find the M.R. of a singly reinforced concrete beam of 200 mm width and 400 mm effective depth,
reinforced with 3 bars of 16 mm dia. of Fe 415 steel. Take M 20 concrete. Determine the actual
stresses when the section is subjected to the limiting moment of resistance.
2. Write short notes about the development length.
A simply supported beam, 300 mm wide and 600 mm effective depth carries a uniformly distributed
load of 74 kN/m including its own weight over an effective span of 6 m. The reinforcement
consists of 5 bars of 25 mm diameter. Out of these, two bars can be safely bent up at 1 m distance
from the support. Design the shear reinforcement for the beam.
Given data: Grade of concrete: M 20
Grade of steel: Fe 415
Assume width of support 400 mm
UNIT II
3. Write short notes about the upper bound and lower bound theorems.
Design a continuous reinforced concrete beam of rectangular section to support a dead load 10
kN/m and live load of 12 kN/m over 3 spans of 6 m each. The ends are simply supported. Adopt
M -20 grade and concrete Fe-415 HYSD bars. Sketch the details of reinforcements in the beam.

4. Write the assumptions and characteristic features of yield lines for analysis of slabs.
Design a circular slab of diameter 5 m which is simply supported at the edges. Live load 4
kN/m2. Assume M-20 grade concrete and Fe-415 HYSD bars. Assume load factors according to
IS:456-2000.

UNIT III
5. Write different types of flat slabs with diagrammatically representation.
Design the interior panel of a flat slab for a ware house to suit the following data:
Given Data: size of ware house 24 m by 24 m divided into panels of 6 m by 6 m
Live load kN/m2
Materials: M-20 Grade concrete
Fe-415 grade HYSD bars.
6. Write the guidelines for proportioning
i. Drops
ii. Column heads
iii. Thickness of flat slab
Design an interior panel of a flat slab of size 5 m × 5 m without providing drop and column
head. Size of columns is 500×500 mm and live load on the panel is 4 kN/m2 take floor finishing
load as 1 kN/m2. Use M20 concrete and Fe 415 steel.
UNIT IV
7. Discuss the steps for designing of deep beams.
A reinforced concrete deep girder is continuous over spans of 9 m apart from center to center
it is 4.5 m deep,300 mm thick, and the supports columns 900 mm in width. If girder supports
a uniformly distributed load of 200 kN/m including its own weight, design the necessary steel
assuming M 20 concrete and Fe 415 steel.
8. Discuss stepwise procedure as recommended for the design of corbels.
Design a corbel to support a factored load of 400 kN at a distance of 200 mm from the face of
a column 300 mm by 400 mm.Adopt M-25 grade concrete and Fe-415 grade HYSD bars. Sketch
the details of reinforced in the corbel.
UNIT V
9. Give the details of Indian standard code requirements of slenderness components like short and
axially loaded tied column.
Design the reinforcements in a column size 400 mm by 600 mm subjected to an axial working
load of 2000 kN.The column has an unsupported length of 3 m and is braced against side sway
in both directions. Adopt M-20 grade concrete and Fe-415 HYSD. bars.
10. Write short notes, on the following and also represent them using diagrams:
i. Isolated column footing
ii. Combined footing
A reinforced concrete column 400 mm by 400 mm supports an axial service load of 100 kN the
safe bearing capacity of the soil at site is 200 kN/m2. Adopting M-20 grade concrete and Fe-415
HYSD bars design a suitable footing for the column and sketch the details of reinforcement.
