What Is Seismic Design for Elevators?
Elevator seismic (the ASME A17.1 — the 8.4; the Chapter 13's) designs (the counterweight's — the derailment's; the retainers'), the seismic switch (the tripping — the 0.15g; the shutdown's), and the hoistway (the drift's — the accommodated; the rails' — the bracketed). The design: the zone's (the 2+ — the required; the 8.4's), the retainers' (the plates' — the derailment's), and the inspection (the acceptance's — the seismic's). The earthquake's — the elevator's secured.

The seismic requirements
The Zone 2+ (the 8.4's — the required; the 0.15g's), the retainer plates (the counterweight's — the derailment's; the 8.4.10's), the seismic switch (the 0.15g — the tripping; the 5.12's), the rope (the retainers' — the hoist's; the 8.4.8's), and the car (the 8.4's — the designed; the sling's).
The hoistway and machine
The rails (the bracketed — the building's; the drift's — the accommodated), the machine (the anchored — the overhead's; the 13's), the doors (the interlocked — the hoistway's; the retained), and the pit (the buffers' — the anchored; the 2.6's).
Operation and inspection
The switch's (the reset's — the manual; the inspection's), the emergency (the power's — the standby's; the 100's), the acceptance (the 8.10's — the tested; the seismic's — the witnessed), and the maintenance (the monthly's — the retainers'; the verified). The elevator's — the seismic's chapter; the 8.4's design.
The bottom line
Design elevators for seismic per ASME A17.1 8.4 in Zone 2+ (counterweight retainer plates, 0.15g seismic switch, rope retainers) — bracket rails for building drift and anchor machines per Ch. 13.
