The United States Nuclear Regulatory Commission-based design response spectrum for the seismic design of nuclear power plants is stipulated as the reference spectrum for ground motion selection. Within the period range(s) of interest, the spectral matching of selected records with the target spectrum ...
However, it has become more common in engineering practice to develop a design response spectrum directly from attenuation relations representing individual spectral ordinates of PSA or PSV.

So, much work is needed to identify and uantify new character- istics of response spectra to address issues concerning the common aspects of ground motion...

However, the spectral acceleration is significantly overestimated for G_IN. Such result may be related to both the IS height irregularity and design approach. In fact, higher flexibility at lower floors reduces the acceleration demand at upper floors and the gravity load design leads to higher ...
In the last decades, design optimization of structures received significant attention to reconcile economic aspects, after the recent advances in computer
response from 30% of the transverse loading. Method 2 The application of the ground motion along the principal axes of individual components. The ground motion must be applied at a sufficient number of angles to capture the maximum deformation of all critical components. 2-2 SEISMIC DESIGN CRITER...
while that due to aliased migration artifacts is steeply dipping, in a kx-ky-ω or 3D running-window. Radon filters may provide some additional artifact suppression leverage. For more irregular acquisition design, the noise estimated using kx-ky or kxky- ω filters can be followed by an adapt...
Per ASCE/SEI 43-19 (2021), a design response spectrum (DRS) is generated as the product of a spectral period-dependent scale factor (SF) and the uniform hazard response spectrum (UHRS) at a mean annual frequency of exceedance (MAFE) equal to the target performance goal. Scale factors are...
The design response spectrum is associated with a specific annual probability of occurrence. PSHA is usually determined by the total probability theorem [27,28]. Fig. 3 demonstrates the PSHA process. Sign in to download hi-res image Fig. 3. Probabilistic seismic hazard assessment process (...
