Multi-layer method is a powerful tool to solve structural engineering problems from a section point of view. This method can solve problems related to non-linear material behavior, different materials at the same section, or aspects related to temperature gradient, among others. Two applications shall be explained in two separate technical papers. In this paper multilayer method shall be used to generate an axial-bending interaction diagram for “I” steel sections. The section shall be studied from elastic and plastic material properties and a parameter shall be proposed (plastic area) in order to obtain the plastic capacity of a section produced by axial forces and bending moment acting simultaneously. Matlab software had been employed to develop the content of this technical paper.
