Design Procedures for Shelter Entrance Structures to Resist Blast Overpressure and Radiation Effects.

摘要

The report presents engineering methods to design hardened entrance structures of nuclear warfare shelters to resist the effects of both blast overpressure and radiation. The design overpressure level can be determined from probability data,and the entrance can be sized to accommodate the required traffic flow. Methods are presented to calculate the reflected pressure on the entrance door for various entrance configurations;procedures are given to design the door structurally to resist the applied loads. Radiation attenuation methods are presented to evaluate the requirement for additional shielding. Various materials are considered to provide more effective economical shields. Summaried of door tests performed in the Operation PLUMBBOB test series are given. (Author)
