| Abstract | Development of long-range nuclear weapons in recent years and the subsequent threat of nuclear war has led to an increased awareness of the need for civilian protection. Adequate shelter design can provide substantial protection against delayed radioactive fallout. Protection can generally be greatly increased by more massive roof construction to shield from overhead sources. Larger roof mass, however, can also greatly affect seismic loading on a structure, particularly in the case of multistory buildings. This paper reviews the nature of destructive radiation and mechanics of radiation attenuation. Fallout shelter analysis techniques are investigated as are methods of seismic structural analysis. An example multistory building is analyzed for radiation shielding potential and for seismic characteristics. Variation of these parameters is observed as a function of variable roof mass. This study indicates that roof mass has very little effect on shielding potential in multistory structures, and that the best protection may be found in interior, or core, regions of central stories. It is further concluded that proper preliminary "slanting" in a design can provide at least minimum recommended shelter protection without varying design concepts or increasing costs. |
