This paper discusses research on the damage of the joint in case of earthquake. The Kashiwazaki Kariwa nuclear power plant suffered damage from the Niigata Chuetsu offing earthquake. In the No.6 reactor building, the universal joint of the overhead traveling crane suffered damage. About this damage, experiment and analysis were conducted using the miniature model of an universal joint. Then, the universal joint of the overhead traveling crane of No.6 is examined. The response acceleration of the reactor building is calculated using the seismic waves observed in the foundation of the nuclear power plant. Using the analysis model of the building, the response acceleration on the rail of the overhead traveling crane was calculated, and the loading torque on the wheel was calculated. Damage of the universal joint was considered from the loading torque. Furthermore, the analysis model of the universal joint was made using 3DCAD, and stress analysis was conducted. By correcting the analytical model, the form from which the stress becomes the minimum is examined, and the proposal of the universal joint for overhead traveling cranes is performed.
