Abstract

The main objective of this paper is to compare the response spectra estimated when using simple amplitude and dual scaling criteria. Three structures with T=0.1, 0.3 and 1.0 are considered for representing the effect of different fundamental periods. These structures are considered on soil type II, medium soil, and the selection of records is based on a region with very high seismic risk. The methodology for selecting the real time histories is applied to find seven pairs of horizontal component of real earthquake records. In case of amplitude scaling , the accelerograms are scaled by spectral acceleration and further by the correction method of Standard 2800.For dual scaling the amplitude scaling is done to match the Housner intensity of the target specturum. In terms of the stability of the goodness of fit observed between the mean response spectrum and the design spectrum for different periods of the structure under analysis, it is concluded that the use of dual scaling offers an attractive tool to obtain sensible estimates of dynamic time-history analysis.
