abstract = {Rocking column-foundation system is a promising design concept for bridge columns to reduce drift responses under earthquake hazards. This study assesses the seismic fragility of the rocking column-foundation system within a probabilistic framework. First, statistical tools are used to sample the class of single-column highway bridges in California that are designed with rocking isolation. The transient drift and rocking responses of the system are solved analytically using the equations of motion that incorporate superstructure mass inertia, column flexibility, the uplift condition, and rocking impact mechanisms. Subsequently, the probabilistic seismic demand analysis is constructed to identify the optimal intensity measures for conditioning the seismic demands of the system under three different conditions: (1) the system remains full contact throughout the time history; (2) the system experiences a coupled response of column vibrating and foundation uplifting; and (3) the system overturns under strong ground excitations. Finally, fragility analyses are conducted to estimate the damage and overturning probability of the rocking system under different levels of earthquake hazards. The superior seismic performance of the rocking system is further verified by comparing its fragility curves with those with the conventional fixed-base condition.<br/> &copy; NCEE 2018.All rights reserved.},
