Study on the Design of Metallic Doors Used for Underground Shelters

Abstract

Digital Object Identifier 10.32754/JMT.2018.2.08 45 Abstract—Ensuring the interior spaces and access routes of underground shelters subjected to extreme loading is a particularly important requirement in order to protect the personnel in any situation. Solid metal doors are currently used for such constructions, but they are not usually designed accurately according to the requirements imposed by the actual norms regarding the explosion action in closed space. The way of manifestation and the effects of an open field explosion differ considerably from the situation of detonation in a closed tunnel, specific to access routes of underground shelters. The present paper aims to determine, for different scenarios, the levels of pressure at the entrance of a shelter in order to determine the input data for an efficient further design of the metallic doors.
