The guidance of technical documents modified using ISO /T R25741.2008 "Earthquake cases of elevators and escalators require assembly
Report (English version).
The main differences between this guidance document and ISO /T R25741.2008 and their causes are as follows.
--- Removed ISO /T R25741.2008 Appendix B, because the appendix is Japan's "Earthquake Resistant Design and Construction Guide (1998 Edition)"
Of the information supplementary document, the content has been added to the Japanese "Elevator Seismic Design and Construction Guide (2009 Edition)", so
This guidance document appendix A adds the corresponding content;
--- ISO /T R25741.2008 quoted the American Standard ASMEA17.1-2004 "elevator and escalator safety norms", including
ASMEA17.1a-2005 Appendix, this Guidance Document cites the US Standard ASME A17.1-2010 as
ASMEA17.1-2010 has superseded ASMEA17.1-2004, including ASMEA17.1a-2005 appendix;
--- ISO /T R25741.2008 cites Japan's "Guide for Seismic Design and Construction of Lifts (1998 Edition)", this Guidance Document
Cited Japan's "Elevator Seismic Design and Construction Guide (2009 Edition)", due to Japan's "Elevator Seismic Design and Construction Guide"
(1998 Edition) has been revised to Japan's "Earthquake Resistant Design and Construction Guide (2009 Edition)".
For ease of use, this Guidance Document has made editorial changes to ISO /T R25741.2008.
--- According to China's national conditions, removed the foreword ISO /T R25741.2008 and the introduction of the terms of the article, because of its existence or not
The understanding and use of this guidance document have no effect;
--- Updated Table 2 of the introduction and Figure 1 of Chapter 5 by adding the most violent earthquakes in the world from.2006 to.2011
Domain and magnitude
--- Introduction 0.5 added Wenchuan earthquake damage to the contents of the elevator, an increase of Table 4;
--- According to ASMEA17.1-2010, modified the guidance in Chapter 2 of this technical document 2.1, "8.4.11.2 speed limit valve" by
Make up "8.4.11.2 speed limit valve and plunger clamp"; at the same time, 2.1, 2.7 and reference "ASMEA17.1-2004, package
Include ASMEA17.1a-2005 Appendix "instead of" ASMEA17.1-2010 ";
--- According to Japan's "Elevator Seismic Design and Construction Guide (2009 Edition)" revised Chapter 3 of the guidance of technical documents 3.1, 3.2
And 3.3, appendix A adds the Japanese "elevator seismic design and construction guide (2009 version)" related to ISO /TR
25741.2008 Appendix B of the terms in order to maintain the integrity and correspondence ISO /T R25741.2008;
--- Deleted [8], [12] and [15] in ISO /T R25741.2008 references and re-numbered them in sequence;
--- Added references [36], [37].

Introduction
0.1 In the event of an earthquake, earthquakes release energy in the form of waves that propagate from the source in all directions. Different shape
Energy waves vibrate the earth's surface in different ways while crossing the earth at different velocities. The fastest wave, the wave that reaches the designated place first
It is called P wave. P wave or compression wave, in the direction of its propagation alternately compress and stretch material. S wave is slower than P wave, followed by P wave
Up, S wave in the vertical direction of its propagation direction up and down and before and after the vibration of the Earth's surface. Surface waves will follow the P wave and S wave arrival. Source .NE-
IC [13].
The magnitude of the earthquake is measured by different measures, namely, the Rickett magnitude and the revised intensity of the Mecca earthquake, and Richter's magnitude
Think it is more accurate. The approximate value is shown in Table 1.

Note 1. Table 1 is derived from the Institute of Seismology at the California Institute of Technology [14] and WIEGEL [12].
The magnitude of the earthquake is determined by the logarithm of the amplitude of the seismic wave, which is recorded by the seismograph. Earthquake level for each additional one Rickett single
The equivalent of 10 times the greater strength of the ground vibration; increase of two units equal to 100 times the greater strength of the ground vibration; according to the logarithmic
Sequence analogy.

0.6 For different earthquakes in various countries, a certain level of seismic protection requirements have been covered in some national standards. ISO /TC
178 considers that consideration of the effects of earthquakes in the design and manufacture of elevators facilitates the provision of uniform guidance worldwide to ensure that personnel
And equipment safety. These countries have seismic experience and the guidance document will provide a reference for the elevator industry.
0.7 The scope of this guidance document is to ensure that, in the event of a general earthquake disaster (such as non-destructive ground vibration
Since the disaster) elevator and escalator in the earthquake area can be safe to run the compilation of special norms.
0.8 The present Guidance Document provides the current code for seismic design of elevators and escalators in different geographical areas, where these areas
The experience has shown that it is effective to provide a reasonable degree of seismic protection. Only include the seismic requirements in these elevator safety standards.
0.9 The guidance document does not include the relevant requirements of the Building Code. However, some applicable building code requirements have also been consulted.
