dc.description.abstractIn this article, the effect of hooked-end fibers with different lengths on the structural performance of RC-FPs fabricated from hybrid fiber-reinforced self-compacting concrete (HFR-SCC) was investigated. For this purpose, a total of 15 full-scale test samples having different plate thicknesses (60, 70, and 80 mm) were produced and tested under bending after a 90-day curing period. Subsequently, load-carrying capacity (P-p), flexural toughness (Fth), and deflection ductility index (mu(u)) of all RC-FPs were found using load-deflection curves obtained from bending tests, while crack patterns were drawn from the samples tested. Besides, high-precision contour plots are proposed to estimate the structural performance values of RC-FPs depending on plate thickness and fiber reinforcing index. As a result, the best structural performance in RC-FPs was obtained from the use of a longer hooked-end steel fiber together with micro steel fiber as a hybrid, followed by the lower length hooked-end steel fibers as singles. Specifically, irrespective of the plate thickness, the hybrid use of longer hooked steel fibers in combination with micro fibers increased the P-p, Fth, and mu(u) values of RC-FPs on average 1.67, 1.76, and 1.57 times, respectively, compared to the control specimens. As for when using the lower length hooked-end fiber as single, the values of P-p, Fth, and mu(u) increased on average 1.57, 1.69, and 1.30 times. Lastly, whereas plate thickness has little effect on improving the structural performance of thin-walled carrier elements such as RC-FPs, adding fibers in different lengths, aspect ratios, and combinations is much more effective. The collective test results demonstrate that using RC-FPs made of HFR-SCC in the roof carrier system of large span structures could improve structural performance, aesthetics, erection time, and earthquake behavior thanks to reduced dead load.en_US
