title = "Effectiveness of multiple unseating prevention devices for bridges under extreme earthquakes",
abstract = "This study is aimed to clarify the effectiveness of multiple unseating prevention devices for bridges under strong near-field ground motions by numerically predicting the ultimate situation of bridges. Unseating prevention devices are designed to work under large earthquakes. Once reaching the ultimate situation, a bridge underwent nonlinear and hysteresis behavior, progressive failure, large geometry nonlinearity and collapse. The Vector Form Intrinsic Finite Element, a new numerical method, is thus employed in this study. A parametric study is performed by using two types of bridges. The input ground motions were recorded in the 1995 Kobe earthquake and are amplified to reveal the minimum intensity of the ground motion at which bridges may unseat. The results demonstrate that multiple unseating prevention devices do not increase even deteriorate the safety of the target bridges as expected. However, the safety of bridges increases as the unseating prevention length increases.",
