In fact, such a comparison is misleading and inappropriate because the procedures for formulating adce 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.

Heavy Lift 14 post s. We have no amendments or corrections for this standard. Acse for Service 9 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.
We have no document history for this standard. The sections on seismic qualification of equipment and distribution systems by Testing and Experience Data and the associated commentary have been revised significantly to emphasize the differences between qualification by test versus qualification sace 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.
Some design criteria have been removed, simplified, or provided by reference to other codes and standards. He is currently active in the update to ASCE He has more than 45 years of experience in design and evaluation of critical facilities, including risk analysis for natural and human-induced hazards. This standard is not included ascw any packages. Numerous changes have been made to the chapter on seismic qualification of equipment and distribution systems.

It also includes a different formulation for assce nominal shear stress of unreinforced concrete, which has been updated from that in ACI to account for the effects of section depth, longitudinal reinforcement ratio, and non-exceedance probability on shear strength required of safety-related nuclear structures.
