21、ctra4.3.1 GeneralThe design ground response spectra are the principal means of defining the seismic design ground motion for engineered SSCs. Ground response spectra for use in design shall be defined at the finished grade elevation of the nuclear power plant or at the foundation elevation of major

22、nuclear structures. Free-field ground surface ground response spectra may also be defined for locations remote from the influence of adjacent structures.Response spectra specified for a reference ground condition (e.g., the design basis ground response spectrum) shall be modified by considering the

23、effects of any intervening rock and soil, so as to produce site-specific spectra at the free-field finished grade or the foundation elevation for use and design. If there is softer rock or overburden above hard rock at the site, a site-specific spectrum shall be defined by propagating hard rock grou

24、nd motion through the intervening rock and soil column to the ground surface.4.3.2 Standard-shape ground response spectra4.3.2.1 GeneralEngineering design of many existing and proposed nuclear power plants is based on standard-shape ground response spectra. The standard-shape ground response spectra

25、 (see Clause 4.3.2.2) may be derived from enveloping of response spectra from earthquakes that are representative of seismic hazard and that have significant energy content corresponding to the dominant frequency range of nuclear power plant SSCs. The standard-shape is anchored to a specified value

26、of an index parameter, typically peak ground acceleration and/or velocity.Plant designs based on standard-shape ground response spectra have been demonstrated to have adequate capacity over the entire frequency range, if an appropriate level of ground motion is used to scale the spectra for the site

27、 seismic hazard. Standard-shape ground response spectra, specified for a bounding value of seismic hazard, can be used in generic nuclear power plant designs to satisfy a range of site and foundation conditions. The development of the standard-shape ground response spectra is described in Clause 4.3

28、.2.2.Notes: (1) The standard-shape response spectrum referred to in this Standard was developed using California earthquakes that were predominantly of magnitude 6 to 7, recorded on soil and soft rock sites at distances from 10 to 50 km (Newmark and Hall, 1978) normalized to 90th percentile velocity

29、.(2) In low seismicity areas, the uniform hazard spectra tend to predict higher ground motions at higher frequencies and lower ground motions at lower frequencies in comparison to the standard-shape ground response spectra, particularly for hard rock site conditions.(3) For plants built in eastern N

30、orth America or a similar seismic region, if the standard-shape ground response spectra do not reflect the expected high frequency content of the seismic ground motions, additional evaluation should be performed to ensure that high frequency-sensitive SSCs can perform their prescribed safety functio

31、ns.4.3.2.2 Determination of standard-shape ground response spectra4.3.2.2.1 The standard-shape ground response spectra may be developed by use of appropriate peak ground motion parameters from CSA N289.2 in conjunction with amplification factors. The amplification factors are representative of the a

The standard-shape is anchored to a specified value

33、of an index parameter, typically peak ground acceleration and/or velocity.The amplification factor shall be obtained from Clause 4.3.2.2.2, 4.3.2.2.3, or 4.3.2.2.4.4.3.2.2.2 The amplification factors specified in Table 1 shall be used to develop standard-shape ground response spectra based on normal

34、ized peak ground motion parameters. The sets of amplification factors defined in Table 1 correspond to three frequency ranges. These factors are referenced to the three seismic ground motion parameters of peak displacement, peak velocity, and peak acceleration, and are used to provide constant ampli

35、fication of ground displacement in the low frequency range, constant amplification of ground velocity in the intermediate frequency range, and constant amplification of ground acceleration in the high frequency range. Typical standard-shape ground response spectra for rock sites normalized to peak g
