Abstract: This paper describes a modeling approach that links the energy required to induce rotational deformations in a representative flexural segment (RFS) to the load-deformation response of FRC structural members governed by flexure. The model determines the properties of the representative flexural segment through materials characterization to describe the energy needed to deform the segment to a specific rotation angle. In an actual structural element, the properties of the RFS are assigned to deformed sections located between rigid sections to reflect the deformed shape as determined by yield line theory. The model, which can be applied to FRC materials with tension softening and strain hardening characteristics, predicts the load necessary to deform a structural element to a specific deflection. The model realistically predicts the load-deformation response of flexural beams and plates made of either tension softening or strain hardening FRC.
