Seismic Performance of High-Performance Fiber-Reinforced Cement-Based Composite Structural Members: A Review.

High-performance fiber-reinforced cement-based composite (HPFRCC) is a class of construction materials that exhibit pseudo-strain hardening behavior under tension after first cracking and gradual softening behavior under compression after crushing. Compared to conventional concrete, the enhanced tension and compression performance make HPFRCC promising for earthquake-resistant structures. Extensive studies have explored the seismic performance of reinforced HPFRCC with different material designs and in different structural forms, while real-world applications are emerging. This paper is intended to summarize the collective knowledge that the research community has gained and to identify future research needs. We review (1) HPFRCC cyclic performance on the material level, (2) seismic performance of reinforced HPFRCC flexural members, including beams and columns, (3) shear-dominant members, covering coupling beams and structural walls, and (4) the behavior and design of HPFRCC beam-column joints. We conclude with key challenges and opportunities for the research and professional community. [ABSTRACT FROM AUTHOR]
