Currently in the field of civil engineering the requirement regarding knowledge blast loads are essential. Every country in the world are having terrorist threats. As the scenario of terrorist attacks are unpredictable neither location nor blast material used. This provides an outline to analysis and design to resist blast loads. We have taken an example model to illustrate evaluation of blast parameters which are used in the analysis. The analysis and design of structures to resist

... ive loads is having utmost importance compared to the conventional type of structures. Where Loading is actually independent of time variation. From past few decades terrorist attacks are becoming a new threat to people lives material used, its quantity, and distance from structure etc. Since we don't know when the blasting activity is going to be happened and type of charge material is used, depends on importance of structure we have to make sure the design of structure should be such that it should resist the failure against blasting activities and to property also. The amount of damage caused to structure is depends upon type of charge. Blast loads, its contribution to structures and other required provisions are opted from Technical Manual 5-1300 and IS 4991-1968.The design method used is Equivalent Static Approach. Analysis of frames of structure is done with software package.
