ACI 544.4R-18 Guide to Design with Fiber-Reinforced Concrete

Reported by ACI Committee 544. — American Concrete Institute, 2018. — 40 p. — ISBN 978-1-64195-019-0.New developments in materials technology and the addition of field experience to the engineering knowledge base have expanded the applications of fiber-reinforced concrete (FRC). Fibers are made with different materials and can provide different levels of tensile/ flexural capacity for a concrete section, depending on the type, dosage, and geometry. This guide provides practicing engineers with simple, yet appropriate, design guidelines for FRC in structural and nonstructural applications . Standard tests are used for characterizing the performance of FRC and the results are used for design purposes, including flexure, shear, and crack-width control. Specific applications of fiber reinforcement have been discussed in this document, including slabs-on-ground, composite slabs-on metal decks , pile-supported ground slabs , precast units, shotcrete, and hybrid reinforcement (reinforcing bar plus fibers).
