RCC Design Test...

The minimum grade of RCC and maximum cement content as per IS 456 : 2000 in severe exposure condition is

An RCC beam of rectangular cross section having overall depth and width as 900 mm and 300 mm respectively. Determine the amount of side face reinforcement required (in mm²) on one face of beam as per the provisions of IS 456:2000.

As per IS 456:2000, the diagonal tension failure in RCC beams depends upon:

The service load over a reinforced structure under the limit state of collapse is

Dead Load = 40 kN/m

Live Load = 60 kN/m

Wind load = 60 kN/m

Earthquake load = 30 kN/m.

An RCC beam of cross-section 300 × 650 mm having an effective cover of 50 mm is exposed to seawater spray. It is given that partial factor of safety considered for steel is 1.5 instead of 1.15 and the grade of concrete to be used for such exposure is M35. Determine the limiting area of Fe 415 steel (tension) required for singly reinforcement (in mm²) section (in nearest multiple of 5) as per IS 456: 2000.

(Take limiting depth of neutral axis as 0.48 times the effective depth of the section.)
