During recent years, from passive defense point of view, owing to increasing terrorist attacks and likelihood of air and missile attacks and bomb explosion in urban areas, building design against blast loads has received special attention. Consequently, offering a solution for dealing with destructive agents is a vital issue since it is related to human life. In this study, first the effects of S-24 rocket explosion is evaluated with FLAC software, using finite difference method by making changes in two parameters; namely shallow foundation embedment ratio and the distance between the center of explosion and footing. Two appropriate solutions have been offered with passive defense approach in terms of economy and operation. The first solution is utilizing Carbon fiber reinforced polymer (CFRP) and the second one is employing Micropile technique which is regarded as a retaining element in modeling. Analyzing results of conducted numerical simulations in this study revealed that the presented solutions decrease the maximum footing displacements 30 and 40 centimeters, respectively.
