To　meet　the　demands　of　static　analysis,　fixed　bearings　that　could　restrict　horizontal　displacement　were　installed　in　a　continuous　beam　bridge.　However,　the　seismic　design　of　a　continuous　beam　bridge　would　be　rather　difficult　in　high　earthquake　intensity　regions　because　of　fixed　bearings.　Some　measures　were　taken　to　improve　the　seismic　performance　of　continuous　beam　bridges　to　some　extent,　such　as　replacing　all　bearings　to　seismic-isolation　bearings.　But　the　seismic　safety　of　continuous　beam　bridges　would　not　be　ensured　by　these　measures　when　subjected　to　earthquakes　exceeding　the　preset　parameters.　Hence,　the　principle　of　sliding-restricting　was　proposed,　which　was　achieved　by　a　Cable-sliding　Friction　Aseismic　Bearing　(CFAB).　Based　on　the　example　of　a　continuous　beam　bridge,　seismic　performance　under　different　types　of　earthquakes　was　investigated　using　a　conventional　method　and　a　sliding-restricting　method.　It　was　found　that　the　initial　gap　and　stiffness　of　strand　cables　were　two　key　parameters　of　CFAB　and　that　the　seismic　force　of　a　fixed　pier　could　be　effectively　reduced　by　CFAB,　but　seismic　displacement　at　the　girder　end　would　be　increased.　©　2014　American　Society　of　Civil　Engineers.
