Task 9: Use Australian Standards AS 3600 and relative code to determine the position of the neutral axis and the concrete and steel stresses produced by a bending moment of 80kNm in the cracked section shown below. Aids for rectangular beam design with the hooks and cogs, curtailment of reinforcement and arrangement of reinforcement 300 mm d₁ -Cc 390 d-d mm nĄ, Ts As Transformed cracked section, singly reinforced beam The section is reinforced with four N28 bars in the bottom with an area of 2480mm2. The modulus of elasticity are Ec =23,500MPa, Es = 200,000MPa Use the gross section approach ignoring presence of steel. Reference: Concrete Structures by R.F. Warner, B.V. Rangan, A.S. Hall and K.A.
