Research output: Contribution to journalArticle


An elevator set up in a high-rise building may cause a problem of elevator rope sway. To solve this problem, the responses of buildingelevator systems are examined based on the Complex Complete Quadratic Combination method and damage risk is evaluated with respect to possible earthquakes in Chuetsu district of Niigata Prefecture and the northwestern part of Chiba Prefecture. It is observed that some positions of elevator car can reduce the damage risk of main rope by shifting the natural periods of the rope away from the natural periods of the building.
