ASME TR A17.1-8.4:2020 pdf free download.Guide for Elevator Seismic Design.
Sample calculations are provided to assist the user in applying ASME A17.l/CSA B44 requirements. Paragraph 3-1 shows examples of when ASME A17.1/CSA B44 seismic requirements are necessary and what force level requirements govern for each case. Paragraphs 3-2 through 3-4 show ASME Al 7.l/CSA B44 requirements using IBC and NBCC applications with SI units. Paragraphs 3-5 through 3-7 show ASM E A 17. 1/CSA B44 requirements using 1BC and NBCC applications with imperial units. imperial dimensional units are used since most of the building codes and standards favor imperial units. The applicable ASME A17.1/CSA B44 code Sections are found under each calculation header. All references to Sections or requirements within each calculation are for ASME A17.1/CSA 1344 unless otherwise specified.
3-1 SAMPLE CALCULATION(S) 1: DETERMINING PROPER SEISMIC REQUIREMENTS AND
FORCES
The forces are based on the applicable building code and
ASME M7.1/CSA 844. The applicable ASME A17.1/CSA
844 Code requirements are 8.4(a), 8.4(b), 8.4.13. and
8.4.14.
3-1.1 SampLe CaLcuLation la
3-L1.1 Given
(a) Building installed in jurisdiction where International Building Code (IBC) 2006 is in effect.
(b) Latest Safety Code for Elevators and Escalators (ASME A17.1/CSA B44) is also In effect.
(c) Building is in Seismic Design Category C.
(d) Building has component importance factor of 1.5.
(e) Building has an Sgç of 0.95.
3-1.1.2 DeterminatIon of Proper Seismic Requirements and Force LeveLs. Per 8.4(a)(1), ASME A17.1/ CSA 844 seismic requirements (Section 8.4) are in effect for buildings with Seismic Design Category C and component importance factor of 1.5. Therefore, Section 8.4 requirements are in effect.
Per 8.4(b)(1), building codes referencing Seismic Design Categories shall use force levels as referenced in 8.4.14.
Per 8.4.14.1(a), the horizontal earthquake component force level will be
NOTE:This minimum is dictated by the requirement that F mustnot be less than 0.3Spsl.W, Minimum force level calculated forcomponents at building base (z/h = 0) would yield 0.23wp.
3-1.1.3 combining Nominal Loads Using AllowableStress Design. The load combinations and load factors
below will be used only in those cases in which theyare specifically authorized by the applicable materialdesign standards. The loads will be considered to actin whichever of the following combinations producesthe most unfavorable effect on the component, fastenings,or supports:
(a) 0.6D + 0.7E(b) 1.0D +0.7E
where E is the earthquake load as defined in 8.4.14.
Detailed examples of these force levels are shown inadditional sample calculations provided in this Technical
Report.
3-1.2 Sample Calculation lb3-1.2.1 Given
(a) Building installed in jurisdiction where NationalBuilding Code of Canada (NBCC) 2010 is in effect.
(b) Latest Safety Code for Elevators and Escalators(ASME A17.1/CSA B44) is also in effect.
(c) Building is in Site Class C.
(d)5% damped spectral response,s.(0.2). is 0.5.(e) Earthquake importance factor for building.lg, is 1.3.0Building is not designated a post-disaster building.g) All connections for the elevator components /systems are rigid connections.
