摘要
对某钢管混凝土拱桥分别沿纵桥向和横桥向输入地震波进行时程分析,以拱肋1/2和1/4处位移作为对比,分析了横撑数量对钢管混凝土拱桥抗震性能的影响并得出相应结论。
The time history analysis of the input seismic waves along the longitudinal and transverse directions of a CFST arch bridges is carried out. Taking the displacement of rib 1/2 and 1/4 as a comparison. The influence of the number of transverse braces on the seismic performance of CFST arch bridges is analyzed and the corresponding conclusions are drawn.
