DESIGN PROCEDURES FOR SHOCK ISOLATION SYSTEMS OF UNDERGROUND PROTECTIVE STRUCTURES. VOLUME I. STRUCTURE INTERIOR MOTIONS DUE TO AIR BLAST INDUCED GROUND SHOCK

Abstract

The primary purpose of this report is to provide guidance for designers of shock isolation systems during the initial phases of design. Volume I presents methods for estimating appropriate free field waveforms and the influence of soil-structure interaction upon interior structure motion. The inherent error in shock isolation design is at least =20%; to reduce this, much more soil test data than is now available will be required. Further, based on purely theoretical arguments, shock isolation per se can be eliminated for much equipment used in hard installations. If isolators are required they should be designed as low frequency systems that impose one g acceleration on the isolated equipment. Increase of the acceleration to be tolerated by the equipment will, in the great majority of instances, reduce neither the rattle space required nor the isolator cost. Methods for making the necessary computations are given.
