The latter may suggest that the ASCE [1] guidelines for concrete cracking is appropriate when the slab experiences heavy cracking but the results should.

Process Consulting 10 post s. This approach can still asxe used. Litigation Support 3 post s. A Challenge to Fla 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.


The two standards are performance based and are written to ensure that structures, systems, ascw components SSCs designed and evaluated in accordance with their provisions meet target performance goals that vary as a function of the seismic design basis. Safety 10 post s. Piping 26 post s.

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 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.


Finally, an entirely new chapter has been added on seismically isolated structures, with emphasis on design and on testing of seismic isolation bearings. Heavy Lift 13 post s.

ASCE 43 – Changes to the Upcoming Revision 2018

Numerous changes have been made to the chapter on seismic qualification of equipment and distribution systems. 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.

The revised Standard delineates between component level and system level inelastic energy absorption factors F m and ascr how adjustments to the component level F m factors results in the system level F m factors.
