Method for Estimating Maximum Response Displacement of Sheds on Viaducts Considering Coupled Vibration Behavior Between the Shed and the Viaduct

抄録

It is considered that the best way to calculate the earthquake response of sheds on viaducts, is to use an integral model of the shed and the viaduct. Calculations based on integral models require a vast amount of work because of the need to understand the structural design of both the shed and the viaduct. This report describes the factors affecting the earthquake response of sheds. A method is proposed for estimating the maximum response displacement of sheds considering the coupled vibration behavior between the shed and the viaduct based on structural design information obtained for the shed and the viaduct. The applicability of this method was verified under the earthquake conditions that appear in the seismic design standards for railway structures.
