WebThe cracking moment of a concrete cross section is defined as: Mcrk = fct,m * Ih/yh. Where: fct,m = average tensile strength of concrete. Ih = inertia of the homogenised cross section. yh = distance from the neutral … WebAt section 1: Uncrack stage. Actual moment, M < Cracking moment, Mcr. No cracking occur. The gross section resists bending. The tensile stress of concrete is below rupture. At Section 2: Boundary between crack and uncrack stages. Actual moment, M = Cracking moment, Mcr. Crack begins to form. The gross section resists bending.
