Re-design the reinforcement and check the deflection for the beam 5B2 shown in DWG-01 of Chapter 1 with the following changes (refer to Question A of 4.2.2 for the original design): (As req = 3380 mm?, vc = 0.786 N/mm?, m = 1.46) i. The center-to-center distance between adjacent beams is changed from 3300 mm to 3500 mm, i.e. the distance between gridlines 6 and 7 is changed to 10 500 mm. i. An additional allowance for 300 mm thick soil is required. i. The width of the beam is increased to 400mm. The design parameters are as follows: Beam overall depth, h = 750 mm Beam breadth, b = 400 mm Slab thickness, h = 160 mm c/c distance btw supports = 9 000 mm Width of support, Sw = 500 mm (similar at both ends) c/c distance btw adjacent beams = 3 500 mm (similar on both sides) feu = 35 MPa fy = 500 MPa fyy = 250 MPa Cover = 35 mm Preferred bar size = 40 mm Preferred link size = 10 mm Allowance for finishes = 2.0 kPa Soil thickness = 300 mm Characteristic imposed load = 5.0 kPa
