Compute the ultimate strength capacity of the positive moment beam design below. f'c= 28 MPa, fy= 414.6 MPa, bf= 760 mm, t= 85 mm, hw= 440 mm, bw = 420 mm ds= 10 mm, ct= 30 mm, cb = 35 mm. Steel bar details: compression side at top (single layer): 3 - 16 mm dia. , tension side (double- layered): upper layer is 4 - 28 mm dia. and lower layer is 4 - 28 mm dia."
