Abstract:

A novel seismic design method, namely split-pier seismic design, is proposed.A vertical gap and connect elements are set in split-piers.The lateral stiffness of piers is reduced by cracking of the connect elements under severe earthquake, and the seismic response of bridges is reduced by avoiding the site predominant periods.A model of tied-arch rigid frame bridge with split-piers was designed.Seismic performance was investigated by pseudo-static experimentation on the scale model.The failure process of split-piers, the hysteresis characteristic and the effect of split-piers on the superstructure are presented.Results show that the split-pier has better seismic performance than common ductile piers do.
