“…In general, the global structural response and failure of the PC, HCC and FRC slabs were quite similar and characterised by the formation of flexural cracks emanating from the centre towards the corners and edges of the slab, as same as reported in other studies on concrete slabs subjected to dropweight impact test (28,29,30,31). However, the local response of HCC slabs was somehow different from the other slabs.…”

ABSTRACT:The performance, under drop-weight impact load, of hybrid cement composite (HCC) elements, consisting of a top layer of plain concrete (PC) and a bottom layer of fibre reinforced concrete (FRC), in comparison with full-depth FRC and PC was studied. Apart from improving the tensile capacity of PC and saving fibre steel reinforcements of FRC, the results showed that HCC can effectively control the deformations and enhance the impact performance of the structural members as its outcomes were similar to that of a full-depth FRC. The analytical studies using Hughes empirical formulae (HEF) and yield line theory (YLT) adopted to investigate the practical use of HCC showed that they are applicable for design such HCC elements against impacts. KEYWORDS: RESUMEN:Comportamiento de elementos estructurales de compuestos híbridos base cemento frente a impacto de torre de caída. Se estudió el comportamiento, frente a impacto de torre de caída, de elementos híbridos base cemento (HCC), formados por una capa superior de hormigón en masa (PC) y una capa inferior de hormigón reforzado con fibras (FRC) en comparación con elementos análogos íntegramente fabricados con FRC y PC. Además de proporcionar una mejora en la resistencia frente a flexo-tracción de los PC y un ahorro en refuerzo usando fibras de acero en el caso de los FRC, los resultados mostraron que el HCC puede controlar eficazmente las deformaciones y mejorar el rendimiento frente a impacto de los elementos estructurales ya que sus resultados fueron análogos a la de los FRC. Los estudios analíticos, utilizando HEF e YLT, adoptados para investigar el uso práctico de los HCC mostraron que los mismos son aplicables para el diseño de estos elementos frente a impacto.

“…The results reveal that the addition of natural fibres increases the impact resistance by 3-18 times than that of the plain mortar slab, and among the four fibres, coir fibre has shown the best performance. Mougin et al [8] reported the protective measurements against rock fall in mountainous areas. Yankelevsky [9] proposed a model to predict the penetration and perforation of concrete slabs impacted by low-velocity missiles.…”
