This paper provides a general overview of recent developments in the study of the flexural post-cracking behavior of steel fiber reinforced concrete (SFRC). The results of three-point-bending tests (3PBTs) performed at the University of Brescia during the last lustrum were collected in a broad database consisting of 81 series for a total amount of 528 beams. Several experimental parameters were investigated: strength of concrete matrix, fiber dosage, fiber aspect ratio, fiber filament tensile strength, as well as fiber orientation. The latter was deeply studied by means of image analysis of cut cross sections. The results, discussed in terms of post-cracking flexural residual strengths, highlight that all the parameters studied contribute to the post-cracking performances exhibited by SFRCs.

“…In their study, a new constitutive model of ECC was proposed with improved compression envelope, reloading curves, and transition curves for tensilecompressive stress transformation compared with the model proposed by Han et al 59 The reloading curve was described using third-order polynomials, as curves (4) and (10) show in Figure 15. The compression envelope was described linearly up to 2/3 peak strain and a nonlinear equation proposed by Saenz beyond that, 65 as curve (8) in Figure 15 shows. The transition curves were described by reloading curves with modified tensile and compressive plastic strain, as curves (6) and (11) in Figure 15 show.…”

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.

“…The seismic behavior of various SFRC members (e.g. SFRC beams, columns, piles, and beam-column joints) has been studied by many researchers (Germano et al, 2013;Lee et al, 2013;Shannag et al, 2003), and the seismic capacity of hollow bridge piers constructed with SFRC has also been investigated in our previous study . However, few researches focused on the seismic demand of SFRC piers and their seismic vulnerability, which are crucial for the seismic risk evaluations of the bridge systems with SFRC piers.…”

Seismic fragility analyses of eight bridge piers, made of steel fiber-reinforced concrete or conventional reinforced concrete, were conducted to reasonably analyze the seismic performance of concrete piers reinforced by steel fibers. The pier specimens were constructed with different steel fiber contents, stirrup ratios, and lengths of the steel fiber-reinforced concrete region. The cyclic load tests on the specimens were carried out to obtain the characteristic values of structural capacity for five damage states. The nonlinear time history analyses of the piers under a suite of selected ground motions were performed to obtain the probabilistic characteristics of structural demand. Using the data related to structural capacity and seismic demand, the fragility curves of these piers were constructed based on an assumed lognormal distribution. The fragility results indicate that (1) the seismic vulnerability of the concrete piers is reduced with the increase in steel fiber content in a certain range, (2) the reinforced concrete pier with a higher stirrup ratio is found to be more vulnerable than the steel fiber-reinforced concrete pier with a relatively lower stirrup ratio, and (3) the fragility of piers adopting steel fiber-reinforced concrete locally and suitably is similar to that of the piers adopting steel fiber-reinforced concrete wholly.
