SECTION-B
Q11. Explain the method of designing a shear key for a retaining wall.
Q12. Design a combined column footing with a strap beam for two RC columns 300 mm ?
300 mm size spaced 4 m apart and each supporting a factored axial load of 750 kN.
Assume BC of soil as 225 kN/sq.m. Use M20 grade concrete and Fe415 grade steel.
Q13. Design a circular water tank with flexible base for a capacity of 450 KL. The depth of
water is 4.5 m. Allow suitable free board.
Q14. Design a rectangular beam 300mm wide is subjected to the following at a section. BM is
40KNm, SF is 30KN and torsion moment is 25 KN-m. Design the section and torsion
reinforcement for M25 grade of concrete and Fy 250.
Q15. Design a footing for a rectangular column 230 ? 450 mm, carries an axial load of 1500
kN. The SBC of the soil is 150 kN/m2 Use M20 concrete and Fe 415 steel.
SECTION-C
Q16. A circular girder of a water tank has a mean diameter of 10 m, and it is supported on six
symmetrical placed columns. The uniformly distributed load on girder is 20 kN/m.
Design the critical sections of the girder using M20 grade concrete and Fe415 grade Tor
Steel and sketch the details of reinforcements.
Q17. A circular beam has to support a circular tank as its bottom ring beam below side wall
and it supported by eight symmetrically spaced circular columns of 400mm diameters.
The inner diameter of water tank is 9m and height of side walls is 3m. Design the ring
beam. Given thickness of base slab is 200 mm. thickness of vertical wall is 250mm. Use
M25 concrete Fe250 steel.
Q18. A staircase of 1.2 m width for an office building consists of each step built into wall with
a bearing of 110mm along the flight with tread = 200mm. Design the staircase and sketch
layout of reinforcement. Use M20 concrete and Fe 415 steel.
