This Standard is intended to be used with ASCE 4, which provides criteria for seismic analysis of safety related nuclear facilities Structures, Systems and Com- ponents (SSCs); AC1 349 for concrete structures; AISC standards for steel structures; ASME standards for me-

13、 chanical systems and components; IEEE standards for electrical systems and components; and ASCE 7 for minimum non-seismic design loads for buildings and other structures. This ASCE Standard specifies seismic load combinations. This Standard uses the Target Performance Goal-based seismic design appr

14、oach documented in U.S. Department of Energy Natural Phenomena Haz- ards (NPH) standards. This Standard is also consistent with the philosophy used in the National Earthquake Hazard Reduction Program (NEHRP) for seismic miti- gation of new and existing facilities. The Standard uses input from ANSVAN

15、S Standard 2.26 to assign Seismic Design Categories (SDCs)” to SSCs. It provides re- quirements for determining design basis seismic load- ing using input from ANSVANS Standards 2.27 and 2.29, and it prescribes design criteria that are tied to structural Limit States. ANS 2.26 employs a graded appro

17、ment. ANS 2.26 specifies five SDCs for classifying SSCs based on their importance and failure consequences. Each SSC has a specified numerical Target Performance Goal. ANS 2.26 also provides descriptive criteria to assist the de- signer in selecting an appropriate Limit State for use in the design o

18、f SSCs. Four Limit States are defined-A, B, C, and D-where A is short of collapse and D is es- sentially elastic behavior. This Standard specifies de- sign criteria for load combinations, including earth- quake ground shaking (i.e., stress, displacement, and ductility limits), such that these Limit

19、States are not exceeded. The combination of SDC and Limit State defines the Seismic Design Basis (SDB) for each SSC. Thus, an SSC with SDB-3C would use criteria for SDC-3 and Limit State C. A total of 20 SDBs are defined in ANS 2.26 that can match seismic design criteria to SSC safety function and i

20、mportance, implementing a graded approach. SDBs defined by SDC 1 and 2 are covered by the approach presented in ASCE 7. This Standard presents design and analysis requirements for SDBs defined by SDC 3,4, and 5 and all Limit States. The approach presented for SDC 3,4, and 5 has been adapted from tha

21、t used in the U.S. Department of Energy Standard 1020, ASCE 4, and the U.S. Nuclear Regulatory Com- mission Standard Review Plan (NUREG-0800). The intended user of this Standard is the designer or analyst involved in the design of a new nuclear structure, system, or component. The Standard is in- te

22、nded to provide a rational basis for the performance- based, risk-consistent seismic design of SSCs in nu- clear facilities. Designers once were initiated into the field of probabilistic design by being taught that seis- mic performance categories for SSCs were established by DOE-STD- 1020-94 and su

23、bsequent revisions. Each performance category was tied to a probabilistic per- formance goal that represented a target annual fre- quency of seismic-induced failure. However, these ear- lier design codes did not allow designers the freedom to select a Limit State (the permissible deformation limit f

24、or the SSC established from functional consider- ations). There has been a movement within the struc- tural engineering community to give designers free- dom to select the desired state of the facility following the Design Basis Earthquake (DBE, defined in ATC- 40, FEMA 273 and FEMA 356, SEAOC-Vision 2000, and ASCE 31). The traditional design Limit State of providing life safety can now be expanded to include nuclear confinement, remain fully functional, or mini- mize operational loss. ix
