Computer Programs for the Analysis of Base-Line Corrected Earthquake Acceleration-Time Histories

摘要

Computer programs are described for the processing of digitised, recorded earthquake acceleration-time histories, assuming that base-line correction of the records has already been performed. A program, SPECTR, is described for the calculation of relative velocity, pseudo velocity, acceleration and displacement response for a particular acceleration-time history. A program, SPECTF, is also described for the calculation of the corresponding Fourier spectra. The acceleration-time history can also be integrated, using a program called VELINT, to produce velocity, displacement and energy input-time histories. (Atomindex citation 08:321820)
