(2) Assume suitable data wherever necessary and specifically mention them.
(3) Figures to the right of each question indicate full marks.
(4) Use of IS456, IS 875 and IS 800 is permitted.
(5) Programmable calculator is not allowed.
1 Design a beam AB; of a building, given in fig-1. Use 10 M-20 grade of concrete and Fe-415 grade of steel. Live load on a slab is 3.0 kN/sqm.
1 Design a rectangular simply supported slab panel of 10
4m x 5m. If the grade of steel is Fe-415 and that of concrete is M-20. The live load on a slab is 2 kN/sq.m.
2 A singly reinforced cantilever rectangular beam section of 8 230 mm width and 450 mm effective depth is reinforced with 4-12 mm diameter bars at top and 2-12 mm diameter bars at bottom. Find out the limiting moment of resistance of a beam, if it is subjected to a hogging moment. Use the grade of steel; Fe-250 and grade of concrete M-15.
3 Write whether the statement is true or false ? Justify 12 your answer :
(i) What is a difference between a one way slab and a two way slab ? What do you mean by a restrained slab ?
(ii) What is the difference between singly reinforced section and a doubly reinforced section ? Under which condition we prefer doubly reinforced section ?
(iii) Explain limit state method, working state method and ultimate state method ? Which one is preferable ? Why?
Explain the behaviour of load bearing structure under 10 the effect of Earthquake. Explain how you will go for detailing to resist earthquake and why ?
Attempt all questions :
(i) How combination of load bearing and framed 2 structure behaves under earthquake ? Will you go
for such combinations, why ?
(ii) What is stiffening element ? Why it is required in 2 load bearing wall ?
(iii) It is required to build cantilever room, having 3m 2 cantilever in both the direction using load bearing structure. How you will provide ? Discuss various options.
Is required to build a hall of size 15 m x 20 m with 7m head room using load bearing masonry wall. With one wall having glass wall. Discuss various options, how you will build this hall ?

Design a shear reinforcements for a simply supported beam of span 5.0 m. Subjected to an 90 kN/m uniformly distributed load in addition to a central point load of 50 kN. The beam section is of 300 mm x 660 mm effective depth. The area of steel required in a tension zone is 1800 sq.mm. Use the grade of steel; Fe-415 and grade of concrete; M-20.
