摘　　要：针对以建筑为主体的建-桥合建高架车站,提出相应的结构性能化设计标准,并通过算例验证了该类高架车站的具体结构性能化设计方法,即车站整体按照建抗规计算,相关构件按照铁抗规及桥抗规复核;这一设计方法综合了建抗规、铁抗规和桥抗规的相关要求,并最大程度满足了上述规范的规定。此外,通过对比计算,比较按照新老规范设计的横向双柱建-桥合建高架车站之间的安全储备差异,得到按照建抗规进行结构性能化设计的车站结果偏于安全的结论。Aiming at the integrated building-bridge elevated station for the building as the main body,the corresponding structural performance-based seismic design standards were proposed,and the specific structural performance-based seismic design method of this type of elevated station was verified through an example.That is,the entire station was calculated according to seismic design codes,and the relevant components were reviewed in accordance with railway seismic design codes and bridge seismic design codes;this design method gave consideration to relevant requirements of seismic design codes,railway seismic design codes and bridge seismic design codes,and met requirements of the above codes to the greatest extent.In addition,through comparison calculations,the safety reserve differences between the horizontal doublecolumn integrated building-bridge elevated station designed in accordance with the new and old codes were compared,to conclude that the structural performance-based seismic design of the station in accordance with the seismic design code is safer.
