parameters:
i) Ultimate Moment of Resistance:
ii) Area of steel:
Mu= 0.156fcubd²
A₁ = M/(0.87f,z)
(b) A rectangular reinforced concrete beam of width b = 300 mm and effective depth d=
430 mm and the design span is 6.5 m. The characteristic strength for the concrete fcu =
25 N/mm² and the steel reinforcement strength f= 500 N/mm². The cover to
reinforcement is 30 mm. Determine the bending reinforcement required for the beam
given the design moment M = 250 kNm.
