Abstract
This paper introduces the factor of stability against overturning (FSO) for curved bridges, and examines the influence of curvature radius and bearing eccentricity on FSO under self-weight and vehicle loads as well as other important parameters. The results show that FSO variation rules are indeed affected by curvature radius and bearing eccentricity. Lane loads are identified as crucial parameters in the overturning resistance of curved bridges. Bearing eccentricity influences the inner side and outer side reactions of abutment bearings, but the optimal bearing eccentricity can ensure uniform torque distribution; said optimal eccentricity is expressed as a function of curvature radius. FSO increases as bearing eccentricity increases, but decreases first followed by a later increase as curvature radius increases. The FSO curve with curvature radius is concave. There exist specific curvature radii near the lowest point in the FSO curve which must be avoided in the design stage to meet necessary safety demands. When curvature radius exceeds 500 m, the FSO converges on an identical curve which can be expressed as a function of curvature radius.
