    Punching Behavior of Hybrid Fiber Reinforced Concrete Panels
    (01. Izmir Institute of Technology, 2020) Naseri, Jamalullah; Saatcı, Selçuk; Saatçi, Selçuk; 03.03. Department of Civil Engineering; 01. Izmir Institute of Technology; 03. Faculty of Engineering
    Hybrid fiber reinforced concrete (HyFRC) is a more recent type of fiber reinforced concrete (FRC), which includes two or more different fibers types. HyFRC may result in a multifunctional material due to synergetic effects of the various type of fibers added in the mixture. In this study, punching behavior of HyFRC thin panels using three different types of steel fibers and polyvinyl alcohol (PVA) fibers were experimentally investigated. In total 13 panel specimens were cast with dimensions of 1700 x 1700 mm2 and thickness of 50 mm. The specimens were simply supported along the edges and loaded through a 150 mm circular steel plate at the center by a displacement-controlled hydraulic actuator. A load cell and fifteen displacement transducers were used to measure the applied load and vertical deflection of the specimens, respectively. All specimens that contained only steel fibers failed under punching. In hybrid fiber reinforced specimens with steel and PVA fibers, either a flexural failure or a punching failure followed by significant flexural deformations were observed. Test results confirm that fiber reinforced concrete has a very significant effect on thin panel's punching strength and displacement capacity. It was seen that hybridization of two different types of fiber, steel and PVA fibers, brings advantages in terms of punching load capacity, deformation characteristics and failure mode.

    Effects of Steel Fiber Type and Ratio on the One-Way Bending Behavior of Hybrid Fiber Reinforced Concrete Thin Panels
    (Elsevier Sci Ltd, 2024) Naseri, Jamalullah; Saatcı, Selçuk; Aloui, Sarra; Naseri, Jamalullah; 03.03. Department of Civil Engineering; 01. Izmir Institute of Technology; 03. Faculty of Engineering
    Performance of hybrid fiber reinforced concrete (HyFRC) determined through standardized material tests usually correlates well with the structural performance. However, for thin panels, this correlation may be disturbed due to the fiber orientation and small crack surfaces, and more detailed investigations are required. In this study, effects of steel fiber type and ratio on the one-way bending behavior of HyFRC thin panels was investigated through concrete mixes obtained by using three different steel fiber types and polyvinyl alcohol (PVA) fibers. 45 dog bone shaped, notched specimens were cast and tested under direct tension to investigate the direct tension behavior of used HyFRC. Nine panels of 2500 x 500 x 50 mm in dimension were tested under three-point bending, and nine panels of 1240 x 500 x 50 mm in dimension were tested under four-point bending. An in-verse analysis to obtain crack width-stress variation in three-and four-point bending specimens was also per-formed and behavior of steel fiber reinforced concrete specimens with and without PVA addition were compared. It was found that steel fiber type and ratio was consistently the dominant factor for all types of tests on HyFRC specimens. Addition of PVA fibers in HyFRC specimens either resulted in a similar or worse behavior for direct tension and three-point bending compared to their steel fiber only counterparts. Adverse effect of PVA fibers was more pronounced in three-point bending tests. On the other hand, PVA addition had a more positive effect in four-point bending tests. Inverse analyses performed on three-point bending tests revealed that stress levels develop between crack surfaces in these thin panels were significantly lower compared to direct tension stress levels. However, under four-point bending, these tensile stresses were closer to direct tension stresses, especially for specimens with shorter steel fibers. Loading conditions were found to be an effective factor in the behavior of HyFRC thin panels.
