Providing architectural patterns for designing hidden buildings against military threats based on the built-in camouflage method

In recent years with the advancement of military technology, societies have become decadent and observation of the ethical principles has declined; different countries attacking each other. One of the most important defensive strategies that have been taken into account by many developed countries, is using passive defense principles for the design of hidden systems according to the patterns of deception and camouflage. The built-in camouflage, has significant advantages compared to the additive camouflage, and it is considered in the original layout when new systems are being designed. This camouflage is a component of system composition and there is no need for personnel effort to activate it. The main objective of this research is to present new patterns for design of hidden buildings and development of resistant structures by the passive method as a defensive strategy. Another goal is to increase the possibility of continuity of their activity in the face of military and terrorist attacks.
