We have no document history for this standard. He formed JJJA in and regularly assembles and manages teams of experts to address complex multi- and interdisciplinary issues and problems, drawing from an extensive group of colleagues for team composition.

Systems 2 post s. The revised Standard delineates between component level and system level inelastic energy absorption factors F m and describes how adjustments to the component level F m factors results in the system level F m factors.

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 section depth, longitudinal reinforcement ratio, and non-exceedance probability on shear strength required of safety-related nuclear structures.

In fact, such a comparison is misleading and inappropriate because the procedures for formulating the performance goals in the two Standards assce 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.
