Abstract:
This paper presents a nonlinear strut-tie model approach for the analysis and design of structural concrete. Nonlinear techniques in the selection, analysis, and verification processes of a strut-tie model are incorporated in this approach to eliminate the limitations of the conventional strut-tie model approach relating to behavior and strength predictions of structural concrete and the design of structural concrete that experiences nonlinear behavior. The additional positioning of concrete ties and steel struts at the locations of steel ties and concrete struts, respectively, is also incorporated in the proposed approach. This new method is illustrated through an analysis example of a simply supported reinforced concrete beam tested to failure, and a design example of a pier structure.
