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. … WebSection stiffness can be evaluated based on moment curvature according to beam equation. Eqn. 3.1. y EI MN φ = (3.1) MN is nominal moment capacity of the section; φy is yield curvature of equivalent bilinear representation of the moment curvature diagram. It is accepted that linearization of moment curvature relation is given by an initial
