The Importance of Structures and Concrete Reservoirs in Passive Defense and Ways to strengthen them

Abstract

Structures and concrete reservoirs are considered as urban strategic installations that should have appropriate robustness in order to achieve passive defense. For example, concrete reservoirs playing an important role in the storage of drinking water and other vital fluids in country are considered among the highly important structures with respect to the kind of their application. This study was conducted using overview method to find a solution for retrofitting of concrete structures against earthquake and explosive loads. Introducing a variety of concrete reservoirs methods, it aims to examine its retrofitting methods. It also examines the effect of factors such as type of architecture and using shear wall on reducing the degradation of a concrete structure against earthquake and military attacks. The results showed that by increasing the length of the shear walls and when roofs are flat in concrete structures, we reduces the explosion degradation through surface air pressure and earth shock effect imposed on structure. Secondly, using a variety of methods of retrofitting methods, we can ensure the strength of urban concrete structures during military and natural crisis.
