An appropriate hazard representation is presented herein for Italy, in an improved version with respect to a recently published one. A key ingredient for its realization was a new set of attenuation equations for spectra

Wavelet analysis is used to identify and approximate energetic acceleration pulses (not velocity pulses) together with their associated frequency and amplitude. The processing of acceleration records with wavelet analysis is capable of extracting acceleration pulse

Six typologies of records are considered: un-scaled real records, real moderately linearly scaled, real significantly linearly scaled, real adjusted by wavelets, artificial generated by two different procedures. The study is spectral shape-based, that is, all sets of records con

https://doi.org/10.1007/b136491ted an ever increasing interest in the determination of reliable displacement spectra for design. The reliability of such spectra is usually restricted by the constraints imposed by high-pass data filtering. Recent studies suggest that response spectra from high-quality digital records are reliable

Undergraduate Lecture Notes in Physicsal displacements (SD. and SD., respectively) are selected to represent the nonlinear deformations of single-degree-of-freedom (SDoF) systems. Within this context, the interaction between these deformation demand parameters and high-pass filtering that is used for removing the long-period noise is ex

Such spectra have, for each soil category, an essentially constant acceleration plateau, .., usually equal to 2.5 times the Peak Ground Acceleration, ., followed by a descending acceleration branch. The period range of the constant-acceleration plateau is larger for softer soils.
