STRUCTURE DESIGN ? III
Subject Code : BACH-409
M.Code : 71024
Time : 3 Hrs. Max. Marks : 60
INSTRUCTIONS TO CANDIDATES :
1. Attempt SIX questions in ALL taking atleast ONE question from EACH UNIT.
2. Missing data, if any may be assumed suitably.
3. Use of IS 456-2000 is allowed.
UNIT-I
1. a) What is the necessity of providing shear reinforcement? 3
b) A simply supported beam 250?400 mm effective depth is loaded with a u.d.l. of
15 kN/m. The effective span of beam is 4.00 m. Design the shear reinforcement if the
tension reinforcement is 4-22mm diameter bars and concrete used is M-20 grade. Use
plainmild steel bars for stirrups. 7
2. a) What are the conditions to design a section as doubly reinforced sections? 3
b) Determine the ultimate M.O.R of a beam 300?550mm. The tension and compression
reinforcement provided at an effective cover of 50mm are 2500 mm
2
and 400 mm
2
respectively. Use M-25 concrete 7 and Fe-500 steel. Take f
sc
= 412 N/mm

UNIT-II
3. Design a reinforced concrete slab for a corridor of 3m width. The slab is supported on
walls of 230 mm width. Design the slab, if the slab is to carry a u.d.l of 5 kN/m
2
as
imposed load. Use M-20 concrete and HYSDFe-415 steel. Apply all checks. 10
4. Design a reinforced concrete slab (with corners held down) for a room of 4m?5m.The
slab is supported on walls of 300 mm width. Design the slab, if the slab is to carry a u.d.l
of 5 kN/m
2
as imposed load Use M-20 concrete and HYSDFe-415 steel. 10
