High Performance Fiber Reinforced Concrete (HPFRC) is characterized by ductile tensile strain-hardening behavior accompanied by multiple narrow cracks. Depending on the mixing design and the fiber type, the ultimate tensile strain of HPFRC ranges between 0.2% and 8%, which can be up to 100 times greater than that of conventional concrete materials. When HPFRC is under compression, fibers can provide a confining effect, similar to that of stirrups, to enhance the compressive strength and ductility. Current work in my laboratory is aimed at developing multifunctional HPFRC and exploring the potential of using HPFRC to enhance structural sustainability and mechanical performance. In this talk, I will highlight a few studies that my laboratory has conducted in order to advance the state-of-the-art knowledge/technology of HPFRC in terms of self-healing performance, mechanical properties, computational models, and new earthquake-resistant structural members.
