Reinforced concrete design Question 3.4 and 3.6
A A reinforced concrete beam of rectangular cross-section, provided with
reinforcement for moment only is subjected to an ultimate shear force V of 400 kN.
The beam size, b = 250 mm, d = 475 mm and material strength fck = 30 N/mm?, and
fyk = 500 N/mm². Is the beam adequate for shear?
3.5 Design the shear reinforcement for a beam with b = 300 mm, d = 550 mm, V = 150
kN, fek = 25 N/mm², and fyk = 500 N/mm².
A T-beam and slab system of a structure are made of beams spaced at 3.0 m with a
clear span of 7.2 m between brickwalls of 250 mm thick. For the T beam he = 100
mm, bw = 300 mm, d = 600 mm. If fck = 35 N/mm² and fyk = 500 N/mm², design
the shear reinforcement. Assume 4H25 tension reinforcements are provided with
variable load = 5 kN/m².
