Abstract

The bridges for Korea High-Speed Railway(KHSR) under construction are supported with pot bearings on the middle pier and with pad bearings on the side piers, respectively. The dynamic analysis on these bridges due to trains with high speed, however, has been performed neglecting the effects of bearings. The objective of this study is investigation on the dynamic behavior of bridge supported by pad bearings. The effects of pad bearings with various flexibilities on the dynamic responses of bridges are studied. From the results of this study, the effects of elastomeric bearing on the dynamic responses of bridge(especially vertical accelerations) may cause undesirable behaviors.
