Investigation on the Impact Behavior of Concrete Panels Subjected to Drop Weight Impact Partheepan Ganesan , S. Purushotham Rao, and Vineela Jalagadugula 1 Introduction Concrete has a privilege as a most extensively used construction materials all over the world. So, the research on concrete to enrich its properties in fresh and also in hardened stage is increasing day by day. Reinforced concrete (RC) slabs are the most crucial element in any construction, whether it is a RC framed structure or it is of a load bearing wall system. Generally, concrete slabs designed for the residential building take into account of dead load, live load, and seismic/wind loads along with the appropriate safety factors for the respective loads. Impact loads are not directly considered in the design process [1]. However, there is a distinct difference in the behavior of the concrete slab experiencing dynamic loads when compared to the behavior of the slab subjected to static loads [2]. Analysis and design of structures subjected to dynamic impact load quite often pose severe complexities. In traditional design, this problem is taken care by performing static analysis using partial safety factors both for the load and the mate- rials. Structures perform quite differently due to impact loads when compared to its behavior under static loads. The load which is applied over a very short period of time is called impact load. Dynamic response of the structure is very important in the case of impact of vehicle on the bridge pier [3], offshore structures subjected to impact forces due to hitting of ship [4] and sudden explosions, projectile impact on protective structures, etc. Studies on impact are of utmost importance as it involves huge amount of investment on resources in building the structures in addition to the precious lives of so many people. Zineddin and Krauthammer [5] have studied the responses of concrete slabs rein- forced in different manners subjected to drop weight impact under different drop P. Ganesan (B ) · S.
