摘　　要：本文通过对铁路站台现浇钢筋混凝土单柱雨棚结构柱试验研究、有限元模拟分析和R-μ规律研究,分析单柱雨棚结构平面外的抗震性能。结果表明:铁路站台现浇钢筋混凝土单柱雨棚结构按照当前规范标准体系进行抗震设计安全,并给出了兼顾安全和经济的抗震设计宏观控制指标。In this paper,the out⁃of⁃plane seismic performance of single⁃column canopy structure on railway platform was analyzed by the experimental study,finite element simulation analysis and R⁃μlaw study.The results show that the cast⁃in⁃place reinforced concrete single⁃column canopy structure on railway platform is safe in seismic design according to the current standard and code system,and the macro control index of seismic design that takes into account safety and economy is given.
