Special Elevator Design For SEISMIC Condition

The paper firstly briefly introduces the differences between normal conditions andseismic conditions of elevator. Based on these differences, we make research and study ofhow to design elevator in seismic conditions for earth quake areas.In the paper, it introduced the elevator codes and standards both in China andinternationals. Some calculation and design are mainly based on Europe Code EN81-77.In the paper, we give out the concept how to design non-standard elevator based onseismic requirements. Make analysis for guide rails and guide rail brackets. In thesecalculations, we introduce a new parameter horizontal accelerate. And introduce how todesign special sling part and emergency guide device.Finally, we introduce the difference of other elevator components, such as, countweight system, who two avoid rope snap with other component in shaft.
