摘要
重点论述了桥梁抗震设计反应谱法的基本概念以及在桥梁设计应用中存在的一些问题,并以位于营盘线道路扩建项目T梁桥抗震的设计计算为例,分析T型桥梁在地震作用下的受力特点、设计应该注意的问题、抗震计算方法,为进行桥梁抗震分析提供参考。
Basic concept of response spectrum method in bridge seismic design and problems existing in bridge design are elaborated emphatically and taking the seismic design and calculation of an expansion project T beam bridge located at Yingpan line road as an example, loading features of T bridge under seismic action, issues needing attention in design and seismic calculation method are analyzed for the reference of bridge seismic analysis.
