Assignment 

Design of Reinforced Concrete Structures

                                       

 Note: Answer the following questions

           Mention the relevant code clauses wherever necessary

           Draw diagrams neatly

       1.   What is Stress Block as per Limit state method? Derive Stress Block parameters from the first principles?

    2.   Design flexural reinforcement for an RC beam of size 250 mm wide and 450 mm deep to resist an  ultimate moment of 220kN m. Assume moderate exposure condition. Use M25 concrete and Fe415 steel. Adopt Limit state method. 

    3.   Determine the ultimate moment of resistance of the beam section. Data given b=230mm, D= 400mm, Asc=3 bars of 20mmdia Ast= 3 bars of 25 mm dia, clear cover = 30mm Use M20 concrete and Fe 415 steel.

    

     4. A floor system consists of a slab 110 mm thick, cast integrally on beams spaced at 3.5 m center to center and spanning over 7m. he beam has width of 300mm and the total depth of the beam including the thickness of the slab is 600mm. Assume mild exposure condition. The floor is to be designed for a service load of 4 kN/m² and 0.6 kN/m² for finishes excluding he self weight of the floor system. Design flexural reinforcement for one intermediate T section using Limit state method. Use M25 concrete and Fe 415 steel.
