Furthermore, an evaluation of the effectiveness of the use of cable restrainers on the overall nonlinear seismic response of seismically isolated highway viaducts is presented. For this purpose, the bridge seismic performance has been evaluated on four different radii of curvature, 100m, 200m, 400m, and 800m, considering two cases: restrained and unrestrained curved viaducts. Depending on the radius of curvature, three-dimensional nonlinear dynamic analysis shows the vulnerability of curved viaducts to pounding and deck unseating damage. In this study, the effectiveness of the use of cable restrainers on curved viaducts is demonstrated. The restrainers not only provide a successful unseating protection but also allow the viaducts to behave uniformly despite the differences on the curvature radius, therefore mitigating the curvature effects.
