WebFor elastic analysis, the elementary equations from mechanics of materials is used: f = My/I. f = stress. M = moment applied to the beam. I = moment of inertia of the cross section. y = distance from the neutral axis. Example 3.1. Consider a plain concrete beam that is 10 inches wide and 30 inches deep. The. Webcr is modified moment of inertia of the cracked section corresponding to (mm4) A similar method is used to get an expression for moment of inertia at a section. unc cr LxI Lx I ( …
