Find and compare the moment-curvature correlated behavior (M-response) of fck = 30MPa and fy = 400MP in reinforced concrete beams on the following cross section using the two methods introduced below. Common weight concrete with unit weight of 24kN/m'3, Ec uses the expression of the Concrete Structural Standard (2012), and the material properties of concrete and rebar are assumed to be secondary parabolic and completely carbonic, respectively. 1Using the method of accurate calculation 2Using the method of simple calculation 3For the settlement method, please get the following four points and connect them. 1) Crack point 2) Compression platform strain 0.001 3) Compression platform strain 0.0015 4) Compression platform strain 0.004 If the condition is not specified in the problem, use the appropriate assumed value.
