摘要
本文以一座3跨曲线连续刚构桥为例,建立桥梁空间动力分析模型,针对地震作用下曲线主梁和薄壁高墩的反应结果变化特点,讨论了曲率半径和系梁共同作用下的地震响应规律,并得出相应研究结果。为曲线连续刚构桥抗震设计提供一定的依据。
In this paper, a three span continuous rigid frame bridge is taken as an example to establish the model of spatial dynamic analysis of the bridge. According to the characteristics of the response of the curved main beam and the thin-walled high pier under earthquake action, the effects of the curvature radius and the tie response law are discussed, and the corresponding research results are put forward. The results provide a basis for the seismic design of continuous rigid frame bridge based on curve.
