Transcribed Image Text:

A rectangular beam of width 300mm and overall depth 450mm is subjected to a factored shear of 350 KN. The tension side is provided with 4- 20mm dia bars. Assuming M25 grade of concrete, clear cover as 25mm and Fe415 steel, comment on the shear design of the beam. The design shear strength of concrete, Tc, MPa for M25 grade of concrete is given as (100 Ast,tc, MPa) (0.25,0.36), (0.50, 0.49), (0.75, 0.57), (1.00, 0.64), (1.25, 0.70), (1.50, 0.74), (1.75, 0.78), (2.00, 0.82), (2.25, 0.85), (2.50, 0.88). (a) Design Shear reinforcement is needed. (b) Minimum shear reinforcement is needed (c) No shear reinforcement is needed (d) None of the above.
