In recent years, due to the increase of the height of the high-rise buildings, the elevator becomes an indispensable facilities. Consequently, during earthquake, as natural periods of a building and an elevator system get close, the movement of the elevator ropes, the compensating ropes and the control cables become important. Moreover, when the ground motion becomes longer, the ropes may hit the wall of the shaft and cause damage to the equipment. In such case, the elevators have emergency stops. However, during the time required for the restoration of the elevators, the building's functions become unavailable. In this research, numerical analysis is used to compute the motion of the elevator's rope. Several manufacturers have used this kind of program in order to evaluate the response of their own elevator systems, but comparisons between all these results are difficult. For this research, the aim is to make the analysis program usable by each manufacturer. In this paper, the displacement of the elevator's rope is computied by the response of the top of the high-rise building, then evaluating the time for elevator to recover to its stable position will be carried out.
