“…To achieve this, two-span SFRC continuous columns under a constant axial load combined with a lateral load (applied either monotonically or in reversed cycles) were studied. The specimens adopted for the present validation purposes were those tested by Kotsovos et al [45] and were referred to as D16-FC30-M and D16-FC30-C in the experimental work under monotonic and cyclic loading, respectively. Their main characteristics are summarised in Fig.…”

a b s t r a c tThe present numerical investigation offers evidence concerning the validity and objectivity of the predictions of a simple, yet practical, finite element model concerning the responses of steel fibre reinforced concrete structural elements under static monotonic and cyclic loading. Emphasis is focused on realistically describing the fully brittle tensile behaviour of plain concrete and the contribution of steel fibres on the post-cracking behaviour it exhibits. The good correlation exhibited between the numerical predictions and their experimental counterparts reveals that, despite its simplicity, the subject model is capable of providing realistic predictions concerning the response of steel fibre reinforced concrete structural configurations exhibiting both ductile and brittle modes of failure without requiring recalibration.

“…To this end, the work presented in this article aims to examine the structural response of statically-indeterminate SFRC columns under reversedcyclic loads using Non-linear Finite-Element Analysis (NLFEA). The column case studies considered have already been examined experimentally by Kotsovos et al (2007) and thus the accuracy of the NLFEA predictions can be readily ascertained. The experiments examined only a limited range of parameters (e.g.…”

“…The model was implemented into a well-known commercial NLFEA package (ABAQUS 2007).

“…The staticallyindeterminate arrangement allows for a study of the effect of fibres on strength, ductility as well as moment redistribution and formation of plastic hinges. The SFRC columns were initially examined experimentally by Kotsovos et al (2007) and the salient features of the column specimens studied are summarised in Figure 1 (b). The SFRC specimens (referred to in the experimental work as D16-FC30-C) were tested with steel fibres added at V f = 0.4%.…”

The present study is aimed at examining the structural response of steel-fibre-reinforced concrete (SFRC) columns under reversed-cyclic loading, which were investigated by means of non-linear finite-element analysis (NLFEA). The focus was on investigating the potential of steel fibres in compensating for reduction in conventional transverse reinforcement [and thus the spacing between shear links was increased by 50% and 100% while the fibre volume fraction ( V f) was increased to 1%, 1.5%, 2% and 2.5%]. This is useful in situations where the latter is required in significant amounts (e.g. in seismic design) leading to congestion and practical difficulties in placing the links. The critical factor in the seismic response is the cyclic nature of the load, which is examined in the present research work. An interesting feature of the present research work is the consideration of statically-indeterminate SFRC columns, information on which is rare as previous research studies have focused on simply-supported beams. To address this, both indeterminacy and axial loads were considered in the present investigation. Calibration work was carried out using existing experimental data and good correlation was established between numerical and test results. Subsequently, parametric studies were carried out using the practical range of fibre dosages, which provided insight into how the steel fibres can help reduce the amount of conventional shear links.
