Examining the Adequacy of the Spectral Intensity Index for Running Safety Assessment of Railway Vehicles during Earthquakes

摘要：

Since the Shinkansen derailment in the 2004 Niigata-ken Chuetsu Earthquake, there has been a strong requirement for railway structures ensuring the running safety of vehicles. This paper examines the seismic behavior of running railway vehicles, and proposes a code-type provision for the Running Safety Assessment (RSA) of vehicles based on the results of comparing the assessment indices of Spectral Intensity (SI) and Peak Velocity (PV). Moreover, a nomogram based on the SI index has been prepared and adopted in a new design code called Design Standards for Railway Structures and Commentary (Displacement Limits) 1.
