“…There have been a number of research efforts directed toward practical applications of HPFRCC materials in structural concrete members, such as coupling beams and beamcolumn connections, as well as in plastic hinge regions of beams, columns, and structural walls (Katzensteiner et al 1994, ACI Committee 544 2002, Kim and Parra-Montesinos 2003, Canbolat et al 2005, Parra-Montesinos 2005, Shannag and Alhassan 2005, Yun et al 2007, Quang et al 2016.…”

A total of 127 plate specimens were fabricated and tested, of various mixture proportions, fiber types, and casting methods, in order to investigate the behavior of both plain concrete and high-performance fiber-reinforced cementitious composite (HPFRCC) specimens under multi-axial loading. The majority of the test specimens were initially fabricated as larger loaf specimens, to achieve proper fiber directionality in the out-of-plane direction, and then cut and trimmed, with steel brush platens used for loading to minimize friction between the testing machine and the plate specimens. The test results indicate that HPFRCC materials can exhibit enhanced biaxial compression performance, compared to plain concrete specimens, due to passive confinement provided by fibers in the out-of-plane direction. The multi-axial behavior of HPFRCC materials obtained from the tests was further used to construct biaxial failure curves, and several modeling parameters have then been derived for nonlinear finite element analysis of HPFRCC planar members subjected to biaxial stresses.

“…In the past 30 years, many researchers have developed the various ECCs with different material configurations and analyzed the according mechanical properties. The research results show that these ECCs behave higher ultimate tensile strain (as shown in Figure 9(a)), better compressive properties, better flexural properties, better resistance to freeze-thaw cycles and better shrinkage resistance (Quang et al, 2016; Zhang and Li, 2002). The better shrinkage resistance is demonstrated by the fact that ECCs do not form large shrinkage cracks when drying and shrinking as traditional concrete materials do.…”

Bridge structures are the important part of lifeline engineering, which are easy to lose their traffic function when subjected to strong earthquakes. Seismic resilient bridge structures are that do not require repair or can be restored to normal operating condition with minor repair after an earthquake, which are mainly characterized by self-centering capacity, damage control capacity and easy repair. Therefore, the bridge structures with seismic resilience have become one of the research hotspots in bridge engineering due to the excellent characteristics. This paper firstly reviews the development of bridge seismic design theory, and then highlights the current status of research on bridge structures with seismic resilience. The seismic resilient bridge structures are divided into rocking bridges, bridges with replaceable members and bridges with high-performance materials, according to the method to achieve the performance recovery of bridge structures. Then the research status of these three kinds of seismic resilient bridge structures is reviewed and summarized systematically. A large number of experimental studies and numerical simulations have presented that the seismic resilient bridge structures have excellent performance recovery capability. In addition, this paper also summarizes the current research status of performance evaluation and design methods of seismic resilient bridge structures, and presents practical engineering applications of typical seismic resilient bridge structures. Finally, the future research directions and development trends of seismic resilient bridge structures are prospected.

“…The experimental studies conducted by Shin et al (2014) and Han et al (2015a) were among limited studies investigating the confinement effect of HPFRCCs in coupling beams detailed following ACI 318M-14 (ACI, 2014). They all implied the potential of HPFRCCs that may contribute to the reduction of reinforcement congestion in coupling beams (Kim et al, 2016;Le-Trung et al, 2011;Quang et al, 2016).…”

The current design method in the ACI building code 318M-14 for reinforced-concrete coupling beams requires complex details, which leads to reinforcement congestion and difficulty in construction. As an original solution for this issue, the use of steel fibres to reduce the amount of transverse and bundled diagonal reinforcement in coupling beams is investigated in this study. In order to estimate the effect of the expected design method, four coupling beam specimens with 2/3 scale subjected to cyclic lateral loads were tested. All specimens were made of steel-fibre-reinforced concrete. One specimen complied with ACI code-specified reinforcement details (for all diagonal, transverse and horizontal bars) and three specimens used bundled diagonal reinforcement with variation in the spacing of stirrups. The global behaviours of the tested coupling beams are discussed, especially focusing on the strength, ductility and energy dissipation capacity as displacement demand increases. The test results illustrate that the lateral force-resisting performance of coupling beams was effectively improved by using steel fibres and bundled diagonal reinforcement, even with a reduced amount of stirrups, compared to that designed following ACI code-specified reinforcement details.
