The Air Force Manual for Design and Analysis of Hardened Structures
Abstract
Methods and procedures are presented for estimating nuclear weapon effects pertinent to hardened structures and for designing and analyzing such structures subjected to these effects. Weapon yields considered range from kiloton through multi-megaton size. Overpressure levels which may be treated range from thousands of psi to less than 5 psi. The free-field environments covered include airblast, cratering and ejecta, ground shock and radiation. The treatment of radiation is restricted to methods for preliminary estimates of mechanical effects and shielding requirements. Methods are presented for translating the free-field environments into loads on, and motions of, aboveground, shallow buried and deep underground structures. The behavior and dynamic response of typical structures and structural elements are discussed. The protection of structure contents, including shock isolation, hardmounting, radiation and EMP shielding, is included. Emphasis throughout the manual is on basic understanding of phenomena and methods which are suitable for hand calculations. The methods are believed suitable for feasibility studies, preliminary designs, and analyses and for establishing bounds on areas where more refined investigation may be necessary. A large number of examples illustrate the use of these methods. An extensive list of references for more detailed and/or sophisticated information and methods is also provided.
