Abstract:
Presents a model providing a simplified yet realistic representation of the ultimate limit state of simply supported reinforced concrete beams subjected to transverse in-plane loading. The model has been developed in compliance with the concept of the compressive force path and is used as the basis for the formulation of a simple design procedure shown to yield design solutions that are both safer and significantly more economical than those obtained by using any of the currently available methods. It is demonstrated that the proposed model and the ensuing design method can be extended easily to apply to any type of skeletal structural concrete configuration in which the model represents the structural elements between consecutive points of inflection, with the interaction between the element in the region of such points being modeled as an "internal hinged support" affected by the provision of transverse reinforcement.
