摘要以基于性能的桥梁抗震设计理论为研究背景,分析了桥梁结构地震需求及其概率模型对于震级和距离这两个重要地震参数的敏感度。研究发现震级对于桥梁结构地震需求及其概率模型具有较大影响,距离的影响则相对较小,两个参数的影响具有耦合性;而且,不同周期的桥梁结构对于震级和距离的敏感度具有一定差异。 Sensitivity of seismic demands and probabilistic seismic demand models of bridge structures on important seismic parameters （i. e. magnitude and distance） is analyzed based on performance-based seismic design of bridges （PBSD）. It can be concluded that effects of magnitude on seismic demands and probabilistic seismic demand models of bridge structures are relatively more significant than distance and effects of magnitude and distance on bridge structures are coupled. Sensitivity of seismic demands and probabilistic seismic demand models of bridge structures with different periods on magnitude and distance is a little different.
