Classical seismic design codes consider behavior factor to assess seismic response of structures proposing simplified equivalent static method and dynamic spectral modal method using response spectrum. Both use a global behavior factor to take into account nonlinear effect of elements response. Nowadays ...
The design spectral response acceleration parameter in the short period range and that at a period of 1.0 s, i.e., SDS and SD1, are 1.0 g and 0.6 g, respectively. The DBE design spectrum is shown in Fig. 11. Download: Download high-res image (192KB) Download: Download full-size ...
Design spectra for engineering practice for such sites are currently not developed. The main impediment of such development is perhaps the lack of observed strong motion data for such as conditions and for relevant earthquake magnitudes (>5). Consequently, the use of observed data for this task ...
The mean spectral shape of selected records was considered to match the service level earthquake (SLE) design response spectrum to ensure the accuracy and applicability of ground motion records. Two ground motion intensities are specified based on the GB 50011–2010 [22]: design Conclusions In an...
This spectral shape is also the shape used for the design of the recently licensed Vogtle Nuclear Station, located south of the Savannah River from the SRS. This report provides a summary of the data base used to develop the design basis earthquake. This includes the seismicity, rates of ...

A methodology to relate the probability of impact, and the probability of different levels of percentage peak, spectral displacement increase over a suite of events with equivalent probability of occurrence. Thus, both analyses provide a design risk assessed for these different design parameters, which...
The ISRS will then be used to design SSCs inside the building. • The ISRS are then used for qualification by shake table tests, or the ISRS are applied to models of the SSCs to calculate their seismic response in terms of movements, loads (forces and moments), and stresses. These ...
The use of local spectral design considering the site classes could facilitate specific analysis for structural building. 3. Results and discussion 3.1. Ground motion parameter from one-dimensional seismic ground response analysis Table 2 presents the summary of ground motion parameters for seismic wave...
