Validation of the second-order analysis of elastic plane frames. This paper shows that in elastic plane frames, the method of tangent stiffness of beam-column Developed by Oran (1973), is very reliable seven in the case of large displacements as shown by Kassimiali's (1983). This results show that this method can be used for he design of structures. This paper Considers only plane structures subjected to loads acting on the sample plane, when one of the principal axis Of cross section is also in the plane and the system remains in the elastic regime.
