Recorded Accelerograms as an Alternative Description of the Seismic Action in the P100-1/2006 Romanian Seismic Design Code

Abstract

A combined method of scaling the recorded accelerograms (in the range of the dominant spectral amplification periods, followed by a scaling in the field of accelerations amplitude) was developed in order to obtain accelerograms for structural design, i.e. a set of design Accelerograms for the application of the provisions of item 3.1.3. Recorded accelerograms” of the P100-1/2006 Romanian seismic design code. All the accelerograms thus scaled should have controlled values of the instrumental Arias-type intensity.
