Oblique Frictional Unilateral Pounding Analysis in Two Successive Curved Bridge (S Type) Segments

The most used life-line structure of the modern day is the bridges, which has been developed significantly, with the most recent introduction being of the curved bridges. They provide an aesthetic look and are also very convenient at various crossings and cross-over. However, curved bridges have been observed to have poor seismic response. Pounding between the adjacent segments, in-plane deck rotation and deck abutment interaction make the curved bridges very susceptible during such activities, resulting in deck unseating, shear failure, torsional failure and the interfacial concrete failure [1].
