An Approach Focused on Multiple Scales for Analyzing Steel Fiber Reinforced Concrete Materials and Structures

Jitendra Kumar Yadav, Er. Vikas Kumar

Abstract


A multiscale approach is proposed for analyzing steel fiber reinforced concrete materials and structures. The micro level involves investigating the pullout behavior of steel fibers embedded in concrete matrix, considering various factors such as straight or hooked end, inclination to loading direction, and interfacial slip. A representative volume element (RVE) is employed to describe composite behavior at the meso-scale, accounting for the bridging effect of fibers crossing an opening crack. The macroscopic level employs the Finite Element Method with the Embedded Crack approach, determining cohesive behavior along macro-cracks and material properties from homogenization of fiber-crack interactions and the RVE.
