WITHDRAWN: Impact Behaviour of Reinforced Concrete Slabs Embedded with Inclined Reinforcements

Abstract

Abstract Reinforced concrete structures are frequently subjected to extreme, primarily impact-induced dynamic loading conditions. There are several studies done by focusing the behaviour of reinforced concrete (RC) slabs under static and dynamic loadings. However, the investigation related to the impact behaviour of RC slabs embedding with non-conventional reinforcement patter is relatively rare. Consequently, an experimental investigation was performed in order to examine the impact behaviour of RC slabs reinforced with inclined reinforcement. A drop weight impact test was performed on RC slab specimens to evaluate the impact force and impact energy properties. A total of four RC slabs of 825 X 825 X 70 mm dimensions were cast. Among that, one specimen was reinforced as conventional pattern and other specimens were reinforced with the inclined configuration of reinforcement assembly with different inclinations along the both Lx and Ly directions. The impact response in terms of failure mode, impact force, impact energy and duration of impact force survived were studied. The results comparison showed that the inclined reinforced RC slab specimen provided with lower inclination survives significant impact force for greater intervals by absorbing higher impact energy than conventional specimens.
