  1. My_test is measured moment at yield stage; Mu_test is measured moment at ultimate stage; My_calc is theoretical momenta at yield stage; Φy is theoretical curvature of column at yield stage; Mu_calc is theoretical momenta at ultimate stage; Φu is theoretical curvature of column at ultimate stage.
