Sentence examples for motion spectra from inspiring English sources
In general, microtremors tend to predict slightly lower values of dominant periods than those calculated by the weak motion spectra.
Tall buildings and flexible structures require a better characterization of long period ground motion spectra than the one provided by current seismic building codes.
The time histories of vertical ground motion are generated from the ground motion spectra that are the functions of track, train, and soil parameters.
It is shown that peak SDOF displacement ductility demand relationships developed based on individual ground motion spectra can lead to unconservative designs, particularly for survival-level, soft soil, and near-fault conditions.

Through adjusting the frequency contents and amplitudes of seed motions, spectrum-compatible time histories are obtained.
However, in case that Chemical Shift Imaging (CSI) is used then a number of issues have to be considered, such as, the long acquisition which can lead to patients' anxiety which is accompanied by head motion producing spectra deterioration, field inhomogeneities that produce large line widths deteriorating the spectra resolution, chemical shift misregistration and outer volume signal bleed [ 17].
The process of generating ground motion response spectra via analyzing actual ground motion measurements is described in the paper.
The efficiency of the piano scale is improved by the analysis of the numerically simulated string motion and spectra of the string vibrations excited by the impact of the hammer.
