THE USE OF UNDERGROUND GARAGES AS PROTECTIVE STRUCTURES IN CASE OF NUCLEAR EMERGENCIES

This paper discusses the use of underground garages as protective structures. Three underground garages are taken as case studies; underground garage at El Darrasa, first underground garage under the Tahrir square and second underground garage under the Tahrir square, in order to investigate the use of several parts of their basement floors as protective structures in case of emergencies. A field study has been conducted to the garages. This study aims to identify; the planning, the design and the general features for each one of them, and to determine whether they can be used as protective structures for citizens in emergencies. The basements of the three underground garages were studied and compared. Their protective factors from radiation (PF) and their numeric capacity for sheltering people were calculated.
