STRUCTURAL PERFORMANCE AND COST COMPARISON OF DIFFERENT SEISMIC RESISTING SYSTEMS FOR URBAN EXPRESSWAY VIADUCT

摘要：

The rational multilevel seismic fortification criteria and performance objectives were discussed for urban expressway viaduct bridges. Two typical continuous girder viaduct bridges,a mainline bridge and a ramp bridge,were analyzed in this work. For each bridge,a traditional ductile earthquake resisting system and an isolation earthquake resisting system were tried out. The detail structural seismic performances corresponding to the two different earthquake resisting systems were compared at each design level of earthquake actions for the two typical bridges. It showed that the isolation earthquake resisting system would result in more desirable seismic performances for both of the two typical bridges. Furthermore,the added costs corresponding to the two different earthquake resisting systems were also compared for the two typical bridges. It indicated that the isolation system would also result in a considerable saving in construction cost.
