12) -- Bommer JJ, Acevedo AB. (2004) The use of real earthquake accelerograms as input to dynamic analysis. Journal of Earthquake Engineering, 8(S1):43–91.
This paper explains the criteria for selecting records in terms of earthquake scenarios and in terms of response spectral ordinates are presented, together with options and criteria for adjusting the selected accelerograms to match the elastic design spectrum. The application of both geophysical and response spectra search criteria is illustrated using compatible scenarios, and the selected records are analysed and adjusted to produce suites of acceleration time-series suitable for dynamic analyses. The paper concludes with suggestions for making use of real records in engineering analysis and design, and recommendations are given for improving the current guidelines provided in seismic design codes.
This well-known article addresses the methods adopted in EC8 and partially relevant with the PEER 2001/09.

This study investigates the influence of duration on damage to an 8-storey RC wall-frame structure using 30 recorded accelerograms with a wide range of durations. The primary influence of the spectral acceleration has been homogenized by scaling and adjusting the accelerograms with wavelets so that they all have a good match to the same smooth response spectra.

A review paper of code provisions regarding selection and scaling of ground motions for bi-directional analysis has, however, revealed that the guidelines provided are frequently inconsistent or are lacking transparency regarding the underlying assumptions. The aim of this study is to shed some light on a number of aspects involved when selecting and scaling records for bi-directional analysis and post-processing results of such analyses.
15) -- Hancock J, Bommer JJ., Stafford, PJ. (2008). Numbers of scaled and matched accelerograms required for inelastic dynamic analyses, Earthquake Engineering & Structural Dynamics, 37: 1585-1607.
This paper considers the response of an 8-storey MDOF RC structure to accelerograms selected, linearly scaled or spectrally matched using five different techniques. The first method consists of selecting real records on the basis of seismological characteristics, while the remaining methods make an initial selection on the basis of magnitude and spectral shape before (1) scaling to the target spectral acceleration at the initial period; (2) scaling to the target spectrum over a range of periods; (3) using wavelet adjustments to match the target spectrum and (4) using wavelet adjustments to match multiple target spectra for multiple damping ratios.
