GATE Civil Engineering (CE) 2014 Shift 1 Solved Paper

A rectangular beam of width (b) 230 mm and effective depth (d) 450 mm is reinforced with four bars of 12 mm diameter. The grade of concrete is M20 and grade of steel is Fe500. Given that for M20 grade of concrete the ultimate Shear strength, τ_uc = 0.36 N/mm² for steel percentage, p = 0.25,and τ_uc = 0.48 N/mm² for p = 0.50. For a factored shear force of 45 kN, the diameter (in mm) of Fe500 steel two legged stirrups to be used at spacing of 375 mm, should be
