BA simply supported 18 m effective span RCC rectangular beam of 500 mm x 1500 mm (overall depth)
section is reinforced throughout with 21 numbers of 25 mm diameter bars in three layers of 7 bars
each at a clear cover of 37.5 mm on tensile face. The reinforcement in the compression face is
4 numbers 25 mm diameter and 1 number 20 mm diameter bars in one layer at an effective cover of
50 mm. The clear cover between the different layers on tension face is 25 mm. M25 grade concrete
and Fe 415 grade steel bars are used in the beam throughout. The beam is laterally restrained
throughout the span.
(a) Find out the maximum bending moment M, at limit state of collapse for the beam section assuming
the stress in compression reinforcement o 0.9566 f, corresponding to tensile stress f, in
tensile reinforcement at the limit state.
(b) What should be the superimposed uniformly distributed load 'w', the beam can carry at working
conditions?
(c) Design the shear reinforcement at support if design shear strength of concrete t, is given as
100A,
