(Civil Engineering)
Time: 3 hours Max Marks: 80
Answer any ONE Question from PART-A
and any THREE Questions from PART-B
Note:Assume suitable data whenever necessary
Use of IS codes & Structural Tables is permitted
PART-A(Marks:32)
1. Design the Flexural Reinforcement for the Rectangular concrete Beam of size 250
mm ×400mm simply supported an two marmarry walls 230mm thick and 6m apart.
The Beam has to carry in addition to its own weight, a distributed live load of
10kN/m, dead load of 5 kN/m and a concentrated dead load of 30kN placed at
the mid span point. Assume that the Beam in subjected to moderate exposure
conditions and grade of steel Fe 415 used.
Draw suitable scale longitudinal section and cross section of the Beam
2. Design a plain concrete footing for a column 300mm × 30mm carrying an axial
load of 330 kN. Assume an allowable soil bearing pressure of 360 kN/m2 at a depth
of 1.0m below ground. AssumeM20 concrete and Fe 415 steel.Draw to scale showing
(a) Plan of the footing
(b) Nominal Reinforcement in sectional elevation
PART-B (Marks:16x3=48)
3. Discuss the merits and demerits of the Traditional methods of design ( Working
stress method and ultimate load method).
4. (a) Discuss in brief basic assumptions of bending theory.
(b) Drive expressions for the position of neutral axis and moment of resistance of
balanced rectangular section.
(c) How do you find the moment of resistance of a beam section?
5. When do steel reinforcements require splicing ? What is the length of bars that are
usually available in the market ? Enumerate the methods used for splicing.
6. Design an axially loaded tied column 400mm x 400mm pinned at both ends with
an unsupported length of 3m for carrying a factored load of 2300KN use M20 grade
concrete and Fe 415 steel.
7. Design a continuous floor slab for an office building 12m long and 4m wide supported
on floor beams spaced at 3m c/c. The live load on slab is 2.5kN/m2. Concrete of
grade M 20 and are used.
