Abstract: Blast is an explosion which is a rapid release of potential energy characterized by eruption enormous energy to the atmosphere. A part of energy is converted to thermal energy radia- tion ( ash) and a part is coupled as air blast and shock waves which expand radially The Finite Element Method (FEM) is a numerical technique to nd approximate solutions of partial di erential equations. It was originated from the need of solving complex elas- ticity and structural analysis problems in Civil, Mechanical and Aerospace engineering. In a structural simulation, FEM helps in producing sti ness and strength visualizations. The solution to the numerical model equations are, in turn, an approximation of the real solu- tion to the PDEs. The nite element method (FEM) is used to compute such approximations The terrorist activities and threats have become a growing problem all over the world and protection of the citizens against terrorist acts involves prediction, prevention and mitigation of such events. Explosive is widely used for demolition purposes in military applications, construction or development works, demolitions, etc. It is, also, a very common terrorist weapon as it is available, easy to produce, compact and with a great power to cause structural damage and injuries. In this report we have explored the available literature on blast loads based on standard structural analysis software with limited linear and non-linear capabilities. Apart from this we have performed mesh sensitivity analysis by taking into account various mesh sizes and corresponding de ection is computed. The analytical results are obtained based on the load vs de ection curve for linear and non linear properties of concrete. It is shown that with the present knowledge and common software, it is possible to perform the analysis of structures exposed to blast loads and to evaluate their response
