Icr is the moment of inertia of the cracked section. The uncracked response and the cracked response under service loads were studied at the beginning of the semester (see Flexure in RC Beams at 3 Stages). Calculating the moment of inertia is a two-step process: first the neutral axis must be located, then the moment of inertia can be calculated.
