Effects of steel bearing performance on global seismic response of a bridge

The present study discusses the effects of a steel bearing performance on bridge superstructure response during a strong ground motion. For this purpose, a hybrid seismic response experiment for a steel bearing is conducted. As a result, a slip-type hysteresis is identified for bridge axis and trans...

Summary:The present study discusses the effects of a steel bearing performance on bridge superstructure response during a strong ground motion. For this purpose, a hybrid seismic response experiment for a steel bearing is conducted. As a result, a slip-type hysteresis is identified for bridge axis and transverse directions, respectively. In this respect, a slip mode as well as a stiffness increase are observed due to existence of space around the pin. Also, the degree of superstructure response is affected by a slip-type hysteresis, particularly in the bridge axis direction.
