Abstract

We proposed the restorability evaluation method for railway structures. In this method, all earthquake motions expected within the design service life are used as the design earthquake and the recovery time after an earthquake is used as the verification index. We also proposed more practical method in which structural conditions with the same recovery time are expressed as a nomogram by performing calculations under various conditions in advance. By using the proposed method, it is possible to design structures that can be easily recovered in the same procedure as the conventional seismic design, and it is expected to shorten the recovery time after an earthquake.
