“…In general, increasing reinforcement ratios reduced the deformation capacity and ductility of RC beams. However, the ultimate drift ratios of RECC beams under cyclic loading were enhanced from 12 to 17% by an increase in reinforcement ratio from 0.73 to 1.5% . Moreover, cyclic loading further reduced the deformation capacity of RECC beams compared to that under monotonic loading and this effect was correlated with the reinforcement ratio.…”

“…For simplicity, the abbreviation ECC is used in this paper. Moreover, extensive experimental study has demonstrated that ECC has great potential for use in structural members to improve or strengthen static mechanical behaviour and seismic behaviour . Therefore, the application of ECC at key structural positions may be an effective way to enhance the seismic performance of structures in regions of high seismic risk.…”

Seismic performance is of paramount importance for structures in regions with high seismic risk. Engineered cementitious composite (ECC) exhibits tensile strain hardening behavior and excellent crack dispersion capacity, as well as good workability. The application of ECC material may be a feasible way to improve the seismic behavior of engineering structures. This paper presents a comprehensive review of experimental and simulation studies concerning seismic behavior of reinforced ECC members and reinforced concrete/ECC composite members. The review is mainly focused on design programs for structural members and their seismic response behavior. The effectiveness of the application of ECC for seismic improvement is discussed. Several design recommendations are provided, based on comparison of the related studies.

“…Although reinforced HPFRCC components often exhibit higher strength and displacement capacity when compared to traditional concrete, research has shown that failure often occurs due to reinforcement fracture as opposed to crushing of the concrete material as is typical in reinforced concrete members [9]. A tensionstiffening effect causes deformation to localize at a single cross section once a dominant crack forms in a reinforced HPFRCC member [10].…”

Research efforts have recently been made to simulate the performance of reinforced highperformance fiber-reinforced cement composites (HPFRCCs) at high levels of deformation. Although constitutive models for HPFRCCs have been developed, selecting appropriate mechanical properties of HPFRCCs in simulations remains a critical aspect to predicting component response in large-scale structures. Additionally, fiber orientation and specimen size are known to significantly impact the tensile and flexural response of HPFRCCs. This paper investigates the simulated performance of reinforced HPFRCC components using tensile properties obtained through various testing and casting methods which result in different fiber orientation. An emphasis is placed on predicting reinforced HPFRCC performance at high levels of deformation, and specifically reinforcement fracture, using total-strain based material models. Recommendations are made for selecting appropriate test-methods and casting-methods for characterization specimens that can improve simulated performance of reinforced HPFRCC components.

Development mechanism of plastic hinge in reinforced engineered cementitious composite beams under monotonic loading

Engineered cementitious composites (ECCs) are materials featuring strainhardening behavior with the formation of multiple cracks. When ECC is incorporated in structural applications such as beam, it is expected to significantly improve their mechanical performance. In this study, finite element analysis is performed to investigate the characteristics of the plastic hinge in reinforced ECC (RECC) beams. The plastic hinge lengths of RECC beams, involving rebar yielding zone, concrete crushing zone and curvature localization zone, are found to be much larger than those for reinforced concrete (RC) beams. Based on the above results, parametric studies on the plastic hinge lengths in RECC beams are conducted to study the influences of the tensile\compressive properties of ECC, yielding strength\hardening modulus\ultimate strain of tensile reinforcement, tensile\compressive reinforcement ratio and beam size. This theoretical study has shown that the existing empirical models for RC beams' plastic hinge length are not applicable to RECC beams which exhibit much longer plastic hinge length. A new empirical equation for predicting the plastic hinge lengths of RECC beams is thus proposed.
