The vibration of elevator ropes and the elevator control driving for rope swaying are examined. The conclusions are summarized as follows. 1. Various ropes have various natural periods, and there is a possibility that either of ropes resonates to the building vibration, even when the elevator cargo stops at evely floor. 2. The amplitude of swaying of 1 m or more continues for several minutes when the rope resonates to the building vibration based on the analytical results ofthe rope behavior in a 40-story model building during an earthquake considering the elevator charactenstics. 3. The rope swaying control driving is found to be effective in preventing damages due to the rope swaying as a result of comparing with former earthquake control driving and rope swaying control driving. 4. Various methods have already been devised for the rope swaying detectcs. Since each method has its own individual features, and close attention should be paid for usage.
