1409 A Basic Study in Construction of Elevator Rope Lateral Vibration Analysis System

Because in high-rise buildings the natural period of the elevator ropes may be close to the natural period of the structure, the large displacement of the rope may cause damages to the equipment and the shaft. In this paper, an elevator rope lateral vibration analysis system has been developed. Moreover, an analysis of the seismic response of a building represented by a single mass, and an analysis of the deflection of the elevator rope have been carried out. In the results of ground motions containing long-period component, the maximal displacement of the rope increase and the three first modes appear.
