ABSTRACT
Japanese seismic safety assessment guidelines for important underground reinforced concrete structures were
substantially revised based on performance oriented design in May 2002. The paper introduces the outlines of the
historical background, basic concept, structural analytical methods, assessment procedures, example of assessment
and safety factors, which were incorporated in the guidelines. The decisive incentive of the wholesale revision was
the damages incurred by underground culvert-type reinforced concrete structures in the Great Kobe Earthquake in
January 1995. Two–box-type culvert models with a scale of 1: with respect to actual structures were
dynamically tested in a laminar sand box placed on a large shaking table. The dynamic structural analytical
methods were verified in light of the experimental evidences.
