SECTION-B

11. What are the codal provisions for the design of flat slabs by equivalent frame method?
12. Discuss the yield analysis of slabs.
13. Design a rectangular water tank resting on the ground having size 10m × 5m × 5m. Use M25 concrete and Fe 415 steel.

14. Design a rectangular slab of size 4m × 6m which is simply supported along the edges and has to carry a service live load of 5 KN/m². Assume coefficient of orthotropy as 0.75. Use M25 concrete and Fe415 steel. The design may be restricted to bending only.
15. Briefly comment on the analysis of deep beams.

SECTION-C

16. Design the stem and heel of a cantilever retaining wall to retain horizontal earthen embankment of height 5m above the ground level. The earthen backfill is having density of 18 KN/m³ and angle of internal friction as 25°. The safe bearing capacity of the soil is 160 KN/m³. The coefficient of friction between soil and concrete is assumed to be 0.45. Use M30 concrete and Fe415 steel.
17. Briefly explain the procedure adopted in the design of chimneys and draw typical cross section showing details of reinforcement (vertical and horizontal).
