When an earthquake occurs, elevators are stopped by seismic triggers for protecting users and themselves. Once elevators are stopped, examination by an engineer is required before restarting operation. By the 1992 Tokyo bay earthquake many elevators stopped although almost no damage was reported. The restoration took more than one day. By knowing relationship between the strong motion indices and elevator stop ratio, restoration work can be more efficient. For example, the control center can determine an appropriate order of restoration. In this study, the relationship between the peak ground acceleration (PGA) and the stop ratio was examined. The relationship between PGA and damage ratio was also investigated to determine the proper stop level. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
