| Outline of Final Research Achievements |
In this study, when elevator cage is moving, a simplified calculation method, based on a single degree of freedom (SDOF) system, for estimating rope displacement during an earthquake by using the building acceleration and ground acceleration has been developed. Influence of tension distribution of the rope and the number of considered vibration mode on the analysis precision are made clear. It is shown that the results of this simplified calculation method agree with those of the conventional finite difference method, within the +20%,-30% error margin.
