Abstract

Calculation of response spectra for blast induced vibrations is necessary to fully understand and, in some instances, comply with frequency or distance-related safe blasting criteria. Fortunately, micro-computer systems costing less that 5000 can be programmed to calculate response spectra from paper as well as FM tape records. The system both digitizes (prepares the record for computer calculation) as well as calculates. Programs for the calculation have been written in BASIC, an easy to understand language used with word processors. In addition to describing the equipment and operation of the microcomputer, the paper will discuss the process of and rules for digitization, use of the computer for record production, and will present a simple physical model for understanding dynamic structural response.
