Regarding the surface fault displacement, its value is difficult to predict and it can inflict devastating damage to structures. Therefore, the structures should ideally be designed and built in ways that provide protection from damage by surface fault displacement. However, for linear structures such as railway structures, it may be impossible to avoid building directly above a fault. In those cases, it is necessary to consider the impact of surface fault displacement which is taken as an earthquake-associated event, in addition to the actions considered in a general seismic design. While many studies have covered the behavior of bridges when impacted by surface fault displacement, far fewer such studies have been conducted on rigid-frame viaducts, with the result that the behavior of these viaducts has been unclear. Therefore, this study looks at how rigid-frame viaducts would behave when impacted by surface fault displacement and, based on the findings, effective countermeasures are proposed. In our study, static nonlinear analysis was conducted on rigid-frame viaduct models composed of lumped beam-spring elements in which the viaducts were subjected to surface fault displacement to clarify the relationship between various magnitudes of displacement input and the models’ stress resultants and deformation. It was found that the impact of surface fault displacement can be reduced by simplifying the structure subjected to displacement; here, “simplifying” means reducing the number of spans and integrating the foundations. By simplifying a viaduct, its collapse can be better controlled upon surface fault displacement.
