Introduction to Fiber Reinforced Concrete (FRC) for tunnel segmental liners with an overview of the ACI guide for precast concrete tunnel segments (ACI 533.5R-20 and ACI 544.7R-16)
Presented by
Parsa Heydarpour, Ph.D., P.E., PMP
As advancements in tunneling and underground construction continue to progress, fiber reinforced concrete (FRC) has become an integral material for enhancing the performance, durability, and sustainability of precast tunnel segmental liners. The integration of fibers into concrete has demonstrated significant benefits, including improved crack resistance, enhanced toughness, and optimized structural performance, making it a viable alternative to conventional reinforced concrete solutions. This session will provide a comprehensive introduction to fiber reinforced concrete, its key material properties, and its application in precast tunnel segmental liners. We will also explore the ACI 533.5R-20 and ACI 544.7R-16 guidelines, which offer critical insights into the design, production, and performance considerations for FRC tunnel segments.
This session is designed for engineers, designers, project managers, and professionals involved in tunneling and underground construction. We encourage an engaging discussion and look forward to sharing knowledge that will contribute to the advancement of fiber reinforced tunnel liner design.
