Analyses of strong motion earthquake accelerograms, Volume III - Response spectra; Part D - Accelerograms IID056 through IID070

Abstract

This is the fourth report of a series presenting earthquake response spectrum curves calculated from corrected ground accelerograms. In the Preface to the first part, Volume III, Part A, Report No. EERL 72-80, there is a summary of response spectrum techniques in earthquake engineering which is available as background material for users of the data. For each earthquake accelerogram, two spectrum plots are given - relative velocity response versus period on a linear scale, and a tripartite log-log plot giving relative displacement, pseudo-velocity, and pseudo-acceleration spectra. The Fourier spectrum is also shown on the linear plot. Digital print-outs of ordinates of the plotted curves are tabulated for each earthquake. The records analyzed in this Volume III, Part D, are the corrected accelerograrn data of Volume II, Part D, Report No. EERL 72-52, and appeared in their uncorrected form in Volume I, Part D, Report No. EERL 71-21.
