In Recent years, there has been an increasing tendency to build resilience to the impact of civilian and military infrastructure due to the increasing number of attacks or calamities. An alternative solution is to improve the impact resistance of such structures is to incorporate different types and dosages of fibres into the concrete that can greatly reduce the damage of concrete structures due to the impact load. This research work focuses on the experimental setup based on Drop Weight Test-Ac1 544. The objective is to build a model for impact energy using variation in plain concrete and fibre reinforced concrete. Furthermore, this research work investigates and describes the impact resistance of fibre reinforced concrete to calculate the reliability of model. Lastly this analytical study is based on testing an experimental model using various mathematical and statistical methods.
