Evaluation of Prefabricated Structural Systems for Providing Decentralization Principle from Tehran

Regarding the results of the research about missile attacks in 1987, 1988 and security threads in Tehran, dispersion principle and decentralization from capital are of the bases of the defense logistic plan. Decreasing Tehran’s dependency to surrounding cities, and renewing and reinforcing residential and service buildings are among main targets in decentralization field from Tehran so that there is defense readiness to confront urban warfare and irregular warfare. Choosing a useful structural system is the most influential part in time and cost rate of construction. In this study, the 15-floor building prototype was modelled with three structural systems, steel Structure with Tree Joist (SS), Reinforcement Precast Concrete structure with NMB connections (RPC) and Isolated Concrete Form panel (ICF) with detailed produced elements in the 3th, 4th and 5th dimensions of building information model. The Exact simulation of all three chosen structural systems were resulted in proposing Isolated Concrete Form (ICF) panel for decreasing the cost of decentralization of Tehran.
