000018439 520__ $$2eng$$aThe seismic vulnerability of skewed bridges has been found to be caused by several factors, including the skew angle of the bridge, pounding between adjacent superstructures, and soil-structure interaction (SSI). In this paper, a straight and 30˚ skewed bridge-abutment model were considered to investigate the effects of skew angle on the seismic response of the bridge. The influence of pounding and SSI were also investigated. The bridge segments were allowed to collide with the abutments and spaced apart so that collision does not happen. The bridge was also fixed on the shake table and founded on sand to study the effects of SSI. This paper focused on the bending moments of the bridge pier and in-plane rotations of the bridge girder. It was found that pounding reduced the bending moments of bridges by up to 23%. When pounding was not considered, the bending moment of the skewed bridge was 0.60 times that of the straight in the fixed base case, but was 1.20 times that of the straight when SSI was introduced. The maximum rotation induced in the bridge girder of the skewed bridge in the SSI case was 2.25 times that of the fixed base case when pounding was not considered. When pounding was introduced, SSI did not have much effect on the maximum rotation induced.
