Abstract

This paper’s focus is on the modeling methodology of (steel) fiber reinforcement in concrete. The orthogonal values of fiber efficiency are presented. Bulk as well as boundary situations are covered. Fiber structure is assumed due to external compaction by vibration to display a partially linear planar structure (Stro- even-concept), which can even be simplified in many practical situations to a partially planar system. The two unknown parameters can be experimentally assessed in a single vertical projection image by orthogonal line scanning. Several boundary conditions are distinguished and the practical case of a thin SFRC plate is evalu- ated. Advantages over a practical but very approximate proposal in the open literature are shown.
