Evaluation of the influence of post-cracking response of steel fibre reinforced concrete (SFRC) on load carrying capacity of SFRC panels
Highlights The results of square panel (SP) test executed on SFRC panels are presented. A numerical model is developed to simulate SP and round panel (RP) tests. Using the model, impact of FRC toughness classes on results of RP test is studied. The load carrying capacity of the RP increases noticeably with f R1k parameter. The energy absorption of the RP is significantly improved by increasing the f R3k/f R1k ratio.
Abstract To develop a reliable methodology for the design of steel fibre reinforced concrete (SFRC) slabs, an extensive experimental program was carried out with SFRC square panels simply supported in their contour. By adopting a moment–rotation approach, a numerical model was developed capable of taking into account the constitutive laws of the SFRC for the prediction of the force–deflection response of variety of panel tests recommended in the international standards. The predictive performance of the model was assessed by considering results available in the bibliography and those obtained on the experimental program. The proposed model was utilized in a parametric study to assess the influence of toughness classes of SFRC on the behaviour at serviceability limit conditions, on the load carrying capacity, and on the deformational response of SFRC round panels.
