In this paper, a constitutive function in form of integration is presented for a nonlinear analysis of structures of linear elements. With applications of a constitutive function, the truss and frame elements material nonlinear stiffness equations are derived. The results shows the convenience in numerical analysis and the ability to solve some difficult problems in tn the structural behavior study both in loading and unloading process by use of the presented constitutive function.
