To evaluate the possibility of negative reaction at seismic isolation bearings subject to seismic load, seismic records of El-Centro and artificial earthquake wave were applied to a single-plate girder bridge with various analytical parameters of curvature radii and skew angles. It is found that seismic analysis using those parameters should be carried out to prevent negative reaction at support.
