3-2 Design Requirements
3-2.1 In all seismicity regions, provide adequate structural support to attach the elements of the
elevator support system as required by the elevator manufacturers design and applicable
codes. The elevator manufacturers shall design the elements of the elevator support
system (all elements that are part of the elevator system, such as the car and
counterweight frames, guide rails, supporting brackets and framing, as well as supports
and attachments for driving machinery, operating devices, and control equipment) with
consideration to lateral seismic forces and displacement of TI 809-04, Paragraph 10-3.h.
The elevator shall also comply with the following:
a. Manufacturer shall design all supports and attachments for machinery and equipment
with an ap equal to 1.0 for rigid and rigidly attached items and equal to 2.5 for nonrigid
or flexibly mounted equipment.
