000011250 520__ $$2eng$$aThe New Zealand Standard, European Standard and the U.S. Standard follow different methodologies for scaling ground motion records according to site conditions when time-history is performed. The New Zealand Standard proposes that the spectrum of each scaled record should match the design spectrum over a range of periods related to the natural period of the structure investigated, and the energy of at least one of these record’s spectra must exceed the energy of the design spectrum. The European Standard recommends that the average spectrum of the scaled records should be always larger than 90% of the design spectrum in a defined range of periods, and the value of the average spectrum at period equal zero should be larger than the value of the corresponding design spectrum. The U.S. Standard advises that in a defined range of periods the average spectrum of the scaled records should be 30% larger than the code spectrum. This study analyses how these differences between scaling approaches affect the results of time-history analyses, and some recommendations for adequate application of record scaling procedures are presented.
