  <dc:description>&lt;div class="NLM_sec NLM_sec_level_1 hlFld-Abstract"&gt;&lt;p&gt;The impact of alternate ground-motion scaling procedures on the distribution of displacement responses in simplified structural systems is investigated. Recommendations are provided for selecting and scaling ground motions for performance-based assessment of buildings. Four scaling methods are studied, namely, (1)&amp;nbsp;geometric-mean scaling of pairs of ground motions, (2)&amp;nbsp;spectrum matching of ground motions, (3)&amp;nbsp;first-mode-period scaling to a target spectral acceleration, and (4)&amp;nbsp;scaling of ground motions per the distribution of spectral demands. Data were developed by nonlinear response-history analysis of a large family of nonlinear single degree-of-freedom (SDOF) oscillators that could represent fixed-base and base-isolated structures. The advantages and disadvantages of each scaling method are discussed. The relationship between spectral shape and a ground-motion randomness parameter, ε, is presented. A scaling procedure that explicitly considers spectral shape is proposed.&lt;/p&gt;&lt;/div&gt;</dc:description>
