摘要
桥梁延性抗震理论及设计方法已被国内外工程界广泛接受,国内外关于桥梁延性抗震设计的研究成果也很多。本文结合一轨道交通线独柱墩的设计,建立结构-桩-土相互作用力学模型,并采用约束混凝土的概念,按《城市桥梁抗震设计规范》(CJJ 166—2011)进行桥墩延性抗震分析,为今后同类桥梁设计提供借鉴。
The ductility seismic theory and design method of bridge have been widely conducted in this field. In this paper, ductility seismic design of single column pier of urban rail transit was introduced. A model was built with consideration of interaction of structure, piles and soil. Concrete confinement effect was analyzed. The ductility seismic design was based on the provisions in Code for Seismic Design of Urban Bridges（ CJJ 166--2011 ）.
