Some aspects of nonlinear inelastic analysis of skeletal reinforced concrete structures are discussed, and the capabilities of a computer program (STRUPL 1) developed by the authors are illustrated. The historical analysis of a reinforced concrete frame for various loading conditions is presented. Structural response is characterized by elastic, inelastic, and total nodal displacements; elastic, inelastic, and total stress iesultants; as well as inelastic strain resultants. Information such as elastic limit reponse, ultimate deformations, collapse load factors, and collapse mechanism is determined and discussed.
