Flexural Behavior of Ultra-High-Performance Fiber-Reinforced Concrete Moment Connection for Precast Concrete Decks

摘要

Ultra-high-performance fiber-reinforced concrete (UHPFRC) has been developed considerably over the past 10 years. One application of UHPFRC is to connect the prefabricated reinforced concrete structural segments, such as beams and column members, to enhance the robust performance of the beam-to-column joint. The highlight of the reported work is that the bonding characteristics inherited by UHPFRC and its likely post-cracking tensile strength have been identified. The work and results must be very informative and can be used in precast concrete structural construction. Some findings are also interesting to the discussers, and are worthy of further discussion.
