Investigation on the Impact Behavior of Concrete Panels Subjected to Drop Weight Impact

Abstract

In this study, the response of different thin concrete panels of size 600 mm × 600 mm × 40 mm with and without reinforcements subjected to low-velocity impact under drop weight impact is carried out. For the purpose of comparison, concrete panels of different configurations such as simple cement concrete (PCC) free of any kind of reinforcements, textile reinforced concrete (TRC), and reinforced cement concrete (RCC) in addition to panels made with self-compacting concrete (SCC) were casted. The drop hammer impact test consists of a ball (weighing 1.8 kgs) with a drop height 600 mm is considered. The following parameters of the drop weight impact loading test such as number of blows for first crack, ultimate failure, and energy absorption characteristics were examined to arrive at the best configurations among the selected categories. It is observed that the panel made with self-compacting concrete has performed superiorly over all other cases considered in this study.
