Check whether the sections shown in Figure 3 are underreinforced or not. If underreinforced, calculate the ultimate moment capacities. Materials are C20 and S420. Use material factors Yms, Ymc. Take As₁ = 5014, A₁ = 1016, and As2 = 5 $16. d=420 mm 50 mm 200 mm As1 300 mm 200 mm 250 mm 560 mm Figure 3 1200 mm As2 300 mm (b) 100 mm Check whether the sections shown in Figure 3 are underreinforced or not.
