QUESTION 2 BEAM DESIGN The cross-section shown below represents an upstand beam for a two 3.1m equal span beam. The analysis produced a hogging moment of 255kNm. The beam is manufactured using grade 30/19 concrete and high tensile reinforcement. The exposure conditions are considered to be moderate. Assume Y25 main reinforcement and R10 for shear reinforcement(stirrups) for the determination of effective depth and with no redistribution of moments. All dimensions are in millimeters 300 475 1 100 200 < 2.1. Determine the suitable area of reinforcement that will resist the hogging moment for the beam. Effective Depth (def) = mm bet eff mm K = found off to 3 decimal digits Depth of compression = mm Required Area of Steel (As required mm 2.2. If the provided area of steel for question 1.1. is 4Y20, determine: Minimum spacing, Smin mm Maximum spacing, Smax Sprovided mm Minimum area of steel, As min = Maximum area of steel, As max = Area of steel provided, As provided = 2 mm 2 mm 2 mm
