11、 their introduction in Appendix F. A17.1/B44 seismic requirements are based on input provided from building code seismic maps and charts. Since the mid-1980s, building codes and their seismic maps and charts have undergone major modifications. These modifica-tions created difficulty for the user to
12、properly apply A17.1/B44 requirements in jurisdictions using the latest build-ing codes. This difficulty necessitated the need to realign the A17.1/B44 earthquake requirements with the latest building codes. The 2013 edition of ASME A17.1/CSA B44 introduces a completely revised Earthquake Safety Sec
13、tion 8.4, realigned with the latest building codes available at the time, IBC 2009 and NBCC 2010.In conjunction with the publication of ASME A17.1-2013/CSA B44-13, this first edition of the Guide for Elevator Seismic Design is being released. The Guide was prepared by the ASME A17.1/CSA B44 Earthqua
14、ke Safety Committee. This Guide is intended as an aid to the user to better understand the history behind the development of the latest building and elevator safety codes, the rationale behind the latest Section 8.4 revisions, and the proper application of the Section 8.4 requirements in conjunction
15、 with a jurisdictions adopted building code.Publication of this Technical Report has been approved by ASME in accordance with the Procedures for Development of ASME Technical Reports.

26、fication of ASME A17.1-2010, Section 8.4, Elevator Safety Requirements for Seismic Risk Zone 2 or Greater1-1 SCOPEThis Guide provides rationale for elevator seismic force determination in Section 8.4. It details ASME A17.1 harmonization efforts with all building codes and sum-marizes the harmonizati
27、on impact on elevator design via force comparisons based on component, component mounting location, and building geographical loca-tion, and provides an International Building Code (IBC) quick reference for seismic requirements and equivalent zone force levels.1-2 INTRODUCTIONFor many years, U.S. an
28、d Canadian model build-ing codes such as the Uniform Building Code (UBC), Standard (Southern) Building Code (SBC), and National Building Code of Canada (NBCC) differentiated the force levels expected during seismic activity by zones. For example, a building in a zone 1 location was expected to see l
29、ower seismic forces than a building in a zone 2 loca-tion. A United States Geological Survey (USGS) map of the U.S. (see Fig. 1-2-1), published in the various build-ing codes, indicated the appropriate zone for any part of the country.Seismic requirements were first specified in ASME A17.1-1981, App
30、endix F. They were based on ANSI A58.1, the American National Standard Building Code Requirements for Minimum Design Loads in Buildings and Other Structures. Seismic force levels that the eleva-tor must withstand would vary based on whether the subject building was in a zone 2 or zone 3 location. Zo
31、ne 1 locations did not have elevator seismic requirements. Therefore, to determine elevator seismic forces for any part of the country, one would review the appropriate, adopted building code for that particular location, deter-mine the zone for that location from the seismic zone map used by that b
32、uilding code, and then reference the appropriate elevator forces for that zone in A17.1.In the mid-1980s, the National Earthquake Hazard Reduction Program (NEHRP) published its Recom-mended Provisions for the Development of Seismic Regulations for New Buildings with new seismic maps from the USGS. I
33、nstead of using zones, these new con-tour maps designated seismic ground motion in terms of a velocity-related coefficient, Av. The ground motion parameter, in addition to other building variables, was input into an equation to determine seismic force lev-els for building structural (buildings) and
34、nonstructural components (elevators, escalators, etc.). Throughout the late 1980s and 1990s, the model building codes Building Officials and Code Administrators International, Inc. (BOCA), UBC, SBC began adopting these new maps and variations of the NEHRP seismic force equation into their codes. In
35、Canada, the 1985 edition of NBCC discarded Canadas traditional seismic zones for seven seismic zones based on the velocity-related seismic zone parameter, Zv.With different building codes using different seismic force equations and no longer using traditional seismic zone maps, the need to properly
36、align the A17.1/B44 seis-mic requirements with the new building codes became imperative. Requirement 8.4.13, introduced in the har-monized ASME A17.1/CSA B44 2000 edition, correlated ground motion parameters (such as Avand Zv) to the tra-ditional seismic zones. Using this correlation, the A17.1/B44
37、requirements could continue to be used as written.For reference, the correlating values were as follows:(U.S.: See A17.1/B44, 8.4.13.1)Zone(s) Affected Peak Velocity Acceleration, Av0 and 1 AvH11021 0.102 0.10 H11349 AvH11021 0.203 and 4 0.20 H11349 Av(Canada: See A17.1/B44, 8.4.13.2)Zone(s) Velocit

39、rence International ASME TR A17.1-8.4 20132(SBCCI) established the International Code Council (ICC). In 2000, ICC began publishing one comprehen-sive code, the International Building Code (IBC). The IBC 2000 code used the latest USGS maps (now contour maps with a ground motion parameter of earthquak
40、e spectral response acceleration) and NEHRP guidelines for its seismic force requirements. ASCE 7-02, recognized as the U.S. standard for seismic force requirements, was referenced by IBC 2003. As with IBC 2000, ASCE 7-02 and later editions referenced the latest USGS maps and NEHRP guidelines as the
41、 basis for its force requirements. Similar to IBC, the NBCC 2005 code used location-specific spectral response acceleration values (published in chart form) and NEHRP guidelines as the basis for its seismic force requirements.Since their introduction in April 2000 and 2005, respec-tively, the IBC an
42、d NBCC 2005 have been ado pted by a majority of jurisdictions as their building code. Because the maps or charts no longer refer to zones or the Avor Zvparameters, A17.1/B44 seismic requirements must now be properly aligned with the IBC and NBCC 2005.A small number of jurisdictions still enforce bui
43、lding codes that predate IBC/NBCC 2005. To ensure complete coverage of all existing building codes, Section 8.4 pro-vides a methodology to ensure elevator design seismic force levels meet either(a) IBC and NBCC 2005 requirements(b) traditional seismic zone requirements(c) requirements of building co
44、des preceding IBC and NBCC 2005, where seismic force levels are based on Avor ZvRequirement 8.4(a) dictates whether seismic design is required based on the enforcing building code require-ments. Requirement 8.4(b) specifies the appropriate seismic force level required for design, based on the enforc
45、ing building code requirements.NOTE: As reproduced fromSeismic Zone MapExcerpted from the 1994 SBCCI Standard Building Code, Copyright 1994.Figure 16-2 Seismic Zone MapExcerpted from the 1997 Uniform Building Code, Copyright 1997.Washington, D.C.: International Code Council.Reproduced with permissio

47、 of IBC/NBCC seismic requirements.For equivalent-sized components, horizontal force levels as specified by each code were compared. From derived force levels, geographic areas that might be impacted with force levels above current A17.1/B44 seismic zone force levels were noted. Since IBC/NBCC force
48、levels vary with component height in the building, force level comparisons throughout the building height were also conducted.Horizontal seismic force levels as dictated in A17.1/ B44, IBC/ASCE 7, and NBCC are specified in 1-3.1 below.1-3.1 Horizontal Seismic Force Levels1-3.1.1 A17.1/B44.
