Abstract
Abstract : The High Explosive Simulation Technique (HEST) is a method of simulating the airblast from a nuclear detonation. HEST cavities are usually designed to match an idealized Speicher-Brode representation of a nuclear airblast overpressure-time waveform, but significant differences often occur. Of particular interest in this report is the high frequency spiking characteristic of HEST cavities and its possible effect upon ground shock and structural response. One product of this work effort was a computer code, FREQRES, which calculates soil or structural response due to an ideal Speicher-Brode airblast waveform input. This response to a Speicher-Brode input can then be compared to the measured HEST response to obtain a qualitative indication of the effects of HEST anomalies. For the test data investigated in this report, the spiking from the HEST records had very little effect upon structural and soil response. FREQRES also provided a quantitative measure of HEST record frequency content transferred to soil and structure response. Keywords: Fourier transform, Nuclear explosion simulation, Frequency response function.
