Seismic Design Criteria for Structures, Systems, and Components in Nuclear Facilities. ASCE. ASCE/SEI ISBN (print): ISBN (PDF). 30 Dec ASCE was initiated by the DOE to integrate the various steps in the seismic design process for nuclear plants. It is scheduled to be. The latter may suggest that the ASCE  guidelines for concrete cracking is appropriate when the slab experiences heavy cracking but the results should.

A Challenge to Fla It also includes a different formulation for the nominal shear stress of unreinforced concrete, which has been updated from that in ACI to account for the effects of acse depth, longitudinal reinforcement ratio, and non-exceedance probability on shear strength required of safety-related nuclear structures.
The sections on seismic qualification of equipment and distribution systems by Testing and Experience Data and the associated commentary have been asde significantly to emphasize the differences between qualification by test versus qualification by test experience data and to also update and clarify the factors to be applied to seismic demand for qualification by test, test experience data, and earthquake experience data required to meet the performance goals of the Standard.

Safety 10 post s. Comments No comments made yet. In fact, such a comparison is misleading and inappropriate because the procedures for formulating the performance goals in the two Standards are fundamentally different, namely, performance is judged in ASCE 7 at the system level building collapse requires the failure of multiple building components whereas performance is judged in ASCE 43 at the component level.

Saturday, 30 December The revised Standard delineates between component level and system level inelastic energy absorption factors F m 43-0 describes how adjustments to the component level F m factors results in the system level F m factors.

Some design criteria have been removed, simplified, or provided by reference to other codes and standards. General Interest 4 post s. Due Diligence 5 post s. The two standards are performance based and are written to ensure that structures, systems, and components SSCs designed and evaluated in accordance with their provisions meet target performance goals that vary as a function of the seismic design basis.

Reliability Improvement 26 post s. This approach can still be used. The restrictions on the use of factors to be applied to seismic demand are also documented. Finally, an entirely new chapter has been added on seismically isolated structures, with emphasis on design and on testing of seismic isolation bearings.
