Cost-Optimization Study of Shelter Entrance Structures to Resist Blast Overpressure and Radiation Effects.

摘要

The blast door is an important part of the nuclear blast resistant shelter. The blast door must be a movable element requiring a support system with a cost very sensitive to the weight and dimensions of the door. A computer program has been developed and is available to study 96door-entrance combinations for various door sizes and radiation-overpressure levels. The relative costs of various doors,entrances,and door-entrance combinations have been evaluated to obtain the most cost-effective combinations. Steel tension membrane doors and reinforced concrete slab doors are the most economical. Aerodynamic triangular obstructions placed in front of a door,sloped doors,and unprotected doors are the most cost-effective. (Author)
