This guide covers specifying, proportioning, mixing, placing, and finishing of fiber-reinforced concrete (FRC). This guide presents information to expand on the provisions of ACI 318, Section 14.8 applied to the design of site-cast precast, or "tilt-up," concrete panels, and to provide a comprehensive procedure for the design of these important structural elements. In addition, this guide provides design recommendations for various support and load conditions not specifically covered in ACI 318. Included are design guidelines for in-plane shear.
