高架车站设计中的三种抗震规范参数比较

比较了《建筑抗震设计规范》、《城市轨道交通结构抗震设计规范》和《铁路工程抗震设计规范》在高架车站设计中所用地震参数的异同,包括地震重现期、反应谱曲线构成、衰减指数等,得到《城市轨道交通结构抗震设计规范》对多遇地震下低烈度区软弱场地的地震作用提高最多,比《铁路工程抗震设计规范》约提高30%,比《建筑抗震设计规范》约提高80%。通过某场地条件下高架车站墩柱截面设计比较,得到《城市轨道交通结构抗震设计规范》比《建筑抗震设计规范》圬工量提高20%。

Comparison of Standard Parameters in Seismic Design of Elevated Station

The "Code for Seismic Design of Buildings","Urban Rail Transportation Structure Seismic Design Code" and "Seismic Design Code Railway Engineering" in the seismic design of elevated station are compared to find their different parameters,including earthquake recurrence period,response spectrum curve and attenuation index.It shows that "Urban Rail Transportation Structure Seismic Design Code" plays greater role for the frequent earthquakes at weak sites,where the anti-seismic action is increased about 30％ compared to the "Seismic Design Code for Railway Engineering",and increased about 80％ compared to the "Code for Seismic Design of Buildings".Through column section design for a reinforcement frame of elevated station,the anti-seismic action is increased 20％ compared to the "Code for Seismic Design of Buildings".
