拼装式双柱桥墩的线性地震反应分析研究

Research on the Linearity Seismic Response Analysis of the Split Mounting Type Doublecylinder Pier

拼装式双柱桥墩由于采用的接头形式不同,分析中应选用不同的计算图式,从而其动力特性具有各自的特点.通过对拼装式双柱桥墩的自振特性及地震反应特点、不同计算图式对地震反应的影响以及地基弹簧刚度对自振特性的影响研究,为类似的此类结构设计提供参考.

The dynamic properties of split mounting type double-cylinder piers are different, because we use the different computation patterns in analysis according to different joints. Through the research of the natural vibration properties, the characteristics of seismic response, the different computation patterns affecting to the seismic response and the influence of the subgrade spring stiffness on natural vibration property, it provides a reference for the similar structural design.
